Cook your ground beef and follow the necessary steps for the taco seasoning.
Remove and set aside, wiping out the pan with a paper towel if needed.
Mix the crema ingredients together, dice the tomato, chop the lettuce, and shred the cheddar cheese.
If you only have the large flour tortilla, trace the tostada with a knife to cut out a smaller one.
Lay down a full-sized tortilla and spread some taco sauce.
Add on your preferred amount of cooked taco meat, and then the tostada.
Spread more taco sauce or some of the crema.
Top with cheese, tomato, and lettuce. Then add the smaller tortilla and fold up the edges to make a wrap (see video).
Heat the oil in a pan and fry until golden brown on each side!
Drizzle with crema or guac, or salsa. Pretty much anything you want!
Enjoy!
