Preheat the oven to 400º Heat a skillet on medium high heat, add the ground beef to the skillet. once the meat is browned, about 5 minutes, add in tomato paste, all seasoning, and onion. Sauté for another 5 minutes.
Add in the hot sauce and/or salsa and mix meat well. Wrap about 6-8 tortillas in damp paper towels and set on a microwave safe plate. Microwave for about 45 seconds to 1 minute.
Working quickly with the warmed tortillas, add about 1/4 cup of the meat mixture and 1-2 tbsp of shredded cheese to the tortilla (add the cheese last). Next, fold over and press the tortilla down on a parchment lined baking sheet. The cheese should hold the shell down.
Bake the tacos for about 10-15 minutes in the oven or until the cheese is crispy and the shell is lightly browned.
Use a spatula to lift tacos to a plate, add garnish and toppings of choice and enjoy immediately or if you need to make two batches, place finished tacos in the microwave on a plate to keep warm (don't cook more) while you cook the next batch. Enjoy!
