In a pan, add 1 tbsp of oil and then add 1 small chopped onion. Sauté it for a minute. Now add ground beef.
Over high heat mix it with a wooden spoon to break down bigger lumps.
Add all the spices and tomato paste. Continue cooking for 4-5 minutes while stirring often. Now add 1 cup of water. Once it comes to a boil, lower the heat and let it simmer for 20 minutes.
Add lemon juice and chopped cilantro. (cilantro is optional)
If your seasoned beef is still watery, increase the heat and let it dry completely.
Let the beef cool down to room temperature.
Lay a warm tortilla, add a spoonful of ground beef, 1/4 cup of cheese, next add tostada, a dollop of cream cheese, and top it with shredded lettuce and tomatoes.
Now fold the tortilla up and over to seal it like a crunch wrap( see video)
Heat up a skillet over medium heat, place the crunchwrap seam side down, and cook until brown, then turn it over and cook on the other side. It'll take about 1-2 minutes per side
Slice in half and serve immediately.
