Add beef, season with salt, and cook for 3 to 4 minutes until it begins to brown.
Add taco seasoning and water and continue to cook, stirring frequently until meat is cooked through.
Add beans and cook for an additional 5 minutes to warm beans.
Serve beef mixture in warm corn tortillas with desired toppings.
Notes
*If you don't have taco seasoning, use a combo of (2 tsp each) chili powder and ground cumin - add in some smoked paprika for some extra smoky sweetness.
