Mix together all the ingredients for aioli taco sauce. Season to taste adding more sriracha, garlic, salsa, salt and pepper to your liking. Set aside.
Heat 2 Tbsp oil in a large oven-safe skillet.
Sear salmon filet for 3 minutes on one side, then turn and sear for 2 minutes on the other side.
Put the skillet of salmon in the oven for 7 minutes or until the salmon is tender and flaky inside.
While salmon is baking, heat black beans in a saucepan on the stove.
Remove salmon from oven and flake it. Set aside with beans and veggies to assemble tacos.
Heat tortillas over a burner on the stove, in skillet or pan or in a tortilla warmer
Fill warm tortillas with salmon, black beans, chopped veggies, cabbage and avocado (if using) and drizzle the whole thing with the aioli taco sauce that you made at the beginning. Squeeze a little lime juice over the top of each.
