Preheat the oven: Start by preheating your oven to 425°F (220°C). Line a baking sheet with parchment paper to prevent the salmon from sticking.
Prepare the salmon: In a bowl, toss 1 lb. salmon fillet with 2–3 tsp taco seasoning and 2 tsp avocado oil, ensuring the salmon is evenly coated. If desired, add a little salt for extra flavor.
Bake the salmon: Place the seasoned salmon on the lined baking sheet. Bake in the preheated oven for about 8 minutes, or until the salmon is cooked through and flakes easily with a fork.
Mix the salsa: While the salmon is baking, prepare the mango corn salsa. In a mixing bowl, combine 1 large diced mango, 1 diced cucumber, kernels from 2 ears of corn, 1/4 cup chopped red onion, and 1/2 cup chopped cilantro. Add 1 tbsp honey, the zest and juice of 1 lime, and 1/2 tsp salt. Mix well and adjust the seasoning to taste.
Soften the tortillas: In a skillet, heat 1/4 cup avocado oil over medium heat. Gently soften the 8 corn tortillas in the hot oil until warm and pliable. Alternatively, you can microwave the tortillas wrapped in damp towels for 30 seconds.
Assemble the tacos: Begin assembling your tacos by placing a layer of refried beans or mashed avocado on each tortilla. Top with a piece of the baked salmon and a generous scoop of the mango corn salsa. For an added pop of flavor, finish with a squeeze of lime juice and a drizzle of honey.
As you prepare the tacos, keep an eye on the cooking process to ensure the salmon reaches your preferred level of doneness. A seasoned cook advises to look for a medium doneness where the salmon remains soft and juicy.
