Brown beef with seasoning and drain.

In another small microwave-safe bowl, nuke beans until hot, about 15 seconds. Stir and set aside.

Place tortilla flat on a microwave-safe plate and nuke until warm, about 10 seconds. Spread beans evenly over the exposed side of the tortilla. Set aside.

Warm shell in the microwave for 30 seconds. Place shell over the bean-covered tortilla --line up the shell's bottom with the tortilla's center, and align the right side of the shell with the right side of the tortilla. Gently press on the inside of the shell's right side to seal. Pick up the entire right half of the taco-tortilla, and fold it over so the left sides align. Gently press on the inside of the shell's left side to seal. (If it cracks a little, that's okay!)

Fill shell with seasoned crumbles, lettuce, and cheese. Enjoy!
