Brown the Beef
Heat a large nonstick skillet over medium-high heat. Add the ground beef and cook for 5–7 minutes, stirring occasionally, until browned and crumbly. Remove the beef from the skillet and place it on a paper towel-lined plate to drain excess grease.
Mix the Base Ingredients
Return the beef to the skillet and stir in the black beans, salsa, water, and taco seasoning. Mix well to combine and bring the mixture to a boil.
Add Tortilla Strips and Cheese
Reduce the heat slightly and sprinkle the tortilla strips evenly over the mixture. Top with shredded Cheddar cheese.
Simmer and Melt
Cover the skillet and let the dish simmer for about 5 minutes, or until the cheese is fully melted and the tortilla strips soften.
Serve
Remove the skillet from the heat. Top with sour cream and any additional toppings you love, such as diced avocado, cilantro, or chopped tomatoes. Serve hot and enjoy!
