Ingredient Substitutions & Tips

  • Beans: Great Northern or navy beans can stand in for cannellini.
  • Tuna: Opt for high-quality tuna packed in oil or water. Yellowfin or albacore work beautifully.
  • Roasted Peppers: Jarred or homemade both work; rinse jarred peppers if overly tangy.
  • Herbs: If you lack fresh herbs, use dried (about one-third the amount), but fresh is best for vibrance.
  • Red Onion: Swap for pickled onions for extra tang, or shallot for milder flavor.
  • No mayo: Unlike classic tuna or bean salads, this version is mayo-free, relying on vinaigrette for creaminess.

Step-by-Step Instructions

Ingredient List

  • 1 (14-16 oz) can cannellini beans, drained and rinsed
  • 1 (5-7 oz) can high-quality tuna, drained
  • 1/3 cup roasted red peppers, chopped
  • 1/4 cup finely sliced red onion or pickled onions
  • 1/3 cup chopped fresh herbs: dill, parsley, chives
  • 1 tablespoon red wine vinegar
  • 1 teaspoon Dijon mustard
  • 2 cloves garlic, minced
  • 3 tablespoons extra virgin olive oil
  • 1 tablespoon oil from jarred roasted peppers (optional)
  • Kosher salt & freshly ground black pepper, to taste

Directions

  1. Mix the Salad Base:
    In a large bowl, combine the drained beans, tuna (flaked gently with a fork), roasted peppers, red onion, and chopped herbs.
  2. Prepare the Vinaigrette:
    In a small bowl, whisk together red wine vinegar, Dijon mustard, minced garlic, olive oil, and (if using) the oil from the roasted peppers. Season generously with salt and pepper.
  3. Toss and Taste:
    Drizzle the vinaigrette over the salad base. Gently toss so the beans don’t break up too much. Taste and adjust salt, pepper, and vinegar as needed.
  4. Serve:
    Enjoy immediately at room temperature, or cover and chill for up to 3-4 days. Before serving from the fridge, let the salad sit out a few minutes to take the chill off and brighten flavors.

Serving Suggestions

  • On Toast: Spoon the salad over grilled sourdough or a slice of rustic bread for an open-face sandwich.
  • In Lettuce Cups: Wrap portions in crisp romaine or iceberg leaves for a low-carb option.
  • As a Sandwich: Tuck into crusty bread for a hearty portable meal.
  • With Crackers: Serve alongside whole-grain crackers as an appetizer or part of a grazing board.
  • Over Greens: Mound atop baby arugula, spinach, or mixed greens for extra freshness.

Health Benefits

This salad is not just easy and flavorful—it’s a nutritional powerhouse suitable for many healthy eating goals:

  • High in lean protein, thanks to tuna and beans.
  • Rich in fiber from beans and vegetables.
  • Low in saturated fat as it relies on heart-healthy olive oil.
  • Contains omega-3 fatty acids (from tuna and olive oil) which support heart and brain health.
  • No mayonnaise or heavy cream, making it good for those avoiding processed dressings.
  • Gluten-free and dairy-free as written.

Nutritional Breakdown (Per Serving, Approximate)

  • Calories: 350-400 kcal
  • Protein: 20-25g
  • Fiber: 6-8g
  • Fat: 14-18g (mostly from olive oil)
  • Sodium: Varies by tuna and beans used (rinse well to reduce)

Tips for Success

  • Use the best tuna you can find—wild, sustainably-caught options add cleaner flavor and firmer texture.
  • Gently toss the salad to avoid breaking up the beans too much.
  • Let it marinate: Allowing the salad to rest 15-30 minutes (or overnight in the fridge) deepens the flavor.
  • Elevate with extras: Try tossing in halved cherry tomatoes, baby arugula, avocado, or a squeeze of lemon juice before serving for extra freshness and color.
  • If making ahead, refresh with extra olive oil and lemon/vinegar to brighten the flavor after chilling.

Variations & Customizations

  • Italian influence: Swap red wine vinegar for lemon juice and add plenty of chopped basil and oregano.
  • Hearty version: Add diced boiled potatoes or hard-boiled eggs for a more filling main dish.
  • Vegan option: Replace tuna with more beans and chopped artichokes or hearts of palm for a plant-based meal.
  • Spicy kick: Add a pinch of crushed red pepper flakes or a few thinly sliced pepperoncini.

Storage and Make-Ahead Tips

  • Refrigerate: Store in an airtight container for up to 3-4 days.
  • No freezing: Beans and tuna lose texture when frozen and thawed.
  • Best served: After a short rest, but before beans get mushy (within 3-4 days).

Frequently Asked Questions (FAQs)
