Step 1: In a large skillet, bring 6 cups of water and 1⁄2 teaspoon salt to a boil over high heat. Add the lemon juice. Gently slide the salmon fillets into the boiling water. Reduce the heat to a low simmer and poach until the salmon is cooked through and opaque, about 5 minutes. Remove from the water and set aside to cool to room temperature, 5 to 10 minutes. When cooled, flake into small pieces.
Step 2: Meanwhile, in a large bowl, combine the bell pepper, onion, jalapeño, capers, lime juice, oil, and remaining 1⁄2 teaspoon salt and mix well. Let the salad stand while the salmon cooks and cools, then gently fold the flaked salmon and cilantro into the salad.
Step 3: Divide the lettuce leaves among four serving plates. Then divide the salmon mixture into 12 portions and spoon a portion onto each leaf. Top the salmon mixture with the sliced avocado, fold the lettuce around the salmon and avocado to form a wrap, and then serve seam-side down.
When you trade a less nutritious food for a higher-quality food without losing the personality of the dish, I call it a “swap.” In this recipe, swap that blood sugar–spiking tortilla for crisp butter lettuce to enjoy a low-glycemic meal that satisfies both your taste buds and your waistline.
