Add chopped onion and garlic, sauté until softened (about 3 minutes).
Stir in sliced mushrooms, cumin, paprika, salt, and pepper. Cook until mushrooms release moisture and are tender, about 7 minutes.
Warm the tortillas in a separate pan for about 1 minute on each side.
Assemble tacos by spooning the mushroom mixture onto each tortilla.
Top with avocado slices, cilantro, and a drizzle of salsa.
Serve with lime wedges for extra zest.
Notes
For a spicier kick, top the tacos with pickled jalapeños or hot sauce. You can also substitute the avocado with a cashew crema for a dairy-free alternative to sour cream.
