For 2 burgers 1. Wash and slice tomato. 2. Slice pickles. 3. Beat egg in a small bowl. 4. Lightly toast slices of multigrain bread. 5. Pat the fillets dry, then season both sides with salt, pepper, and paprika. 6. Dip each fillet in beaten egg, then coat evenly with breadcrumbs. 7. Heat oil in a skillet over medium heat and fry the fish 3–4 minutes per side, until golden brown and cooked through. Drain on paper towels. 8. Mix mayonnaise and ketchup in a small bowl. 9. Spread the ketchup–mayo sauce on each slice of toasted multigrain bread. Layer lettuce, tomato slices, pickles, and the crispy fish fillet. Top with the second bread slice. * For extra crunch, toast the bread slightly longer and add a few fresh onion rings if you like.
