Heat your skillet over medium-high heat. Add the protein and break it into small crumbles with a spatula. Once browned (about 5–7 minutes), drain excess grease, then stir in taco seasoning and 1/3 cup water. Let simmer for 2–3 minutes until saucy. Taste and add a pinch of salt if needed.
Wrap tortillas in a damp paper towel and microwave for 30 seconds, or heat them individually in a dry skillet for 10–15 seconds per side. Keep them wrapped in a clean kitchen towel to stay warm and pliable.
Arrange all toppings in small bowls for easy access. Squeeze lime juice over avocado slices to prevent browning, and place sauces like salsa or sour cream in easy-to-drizzle containers.
Layer the protein first, then add veggies and cheese. Top with a dollop of sour cream, a sprinkle of cilantro, and a lime wedge for squeezing. Fold gently and enjoy immediately!
