A take on the classic tuna salad and melted-cheese sandwich, this mackerel salad sandwich recipe uses fish that’s responsibly sourced and equally delicious. A mild, surprisingly meaty little fish, our tinned wild Atlantic mackerel is an excellent source of protein and vitamin D, and has over 500 mg of omega-3s per serving—all without the accumulated toxins associated with large predator fish like tuna and swordfish.

For the Mackerel Salad

• 2 tins Patagonia Provisions Roasted Garlic Mackerel fillets, drained and separated into fat flakes
• 1 celery stalk, diced small
• 1 small shallot or 1/4 red onion, diced small
• About ⅓ cup roughly chopped flat-leaf parsley leaves
• 1 tbsp. mayonnaise
• 1 tbsp. lemon juice plus 1 tsp. lemon zest
• 1 tsp. dijon mustard
• Salt and pepper

For the Sandwiches

• 4 slices muenster cheese (3-4 oz.)
• 6-8 dill pickle chips, drained and patted dry (optional)
• 4 slices rye bread
• 3-4 tbsp. salted butter, softened

Putting It All Together

1. In a medium bowl, gently mix mackerel salad ingredients together.
2. Heat a nonstick pan over medium heat.
3. Assemble sandwiches: Lay a cheese slice on a slice of bread. Add 3-4 pickle chips, half of mackerel salad, and another cheese slice; top with bread. Repeat for second sandwich.
4. Smear tops of sandwiches with half the softened butter. Place sandwiches in pan, buttered side down, then butter the top sides. Cook until golden brown and cheese is melted, about 5 minutes per side.
