First step: buy some real masa harina (corn tortilla flour from a latin american grocery store, its very different from cornmeal)
Second step: Make the tortillas as per package directions. The dough you make will not be elastic like wheat dough, so the easiest way to make tortillas is to make a ball of dough, drop it on a parchment paper, then flatten it with another piece of paper. Drop the flattened piece of dough on a hot lightly oiled pan and fry it until browned on both sides. Keep the tortillas warm in the oven covered with foil. Doesn't matter if they're not super thin.
One package of veggie ground round
2 tsp of freshly ground cumin
2 tsp of freshly ground coriander
About 1 1/2 tbsp of chipotle chiles in adobo sauce
some adobo sauce (be careful, its SPICY)
5 cloves garlic
one onion, diced
some water to moisten, or tomato paste
chopped fresh coriander
Add fresh tomatoes, cucumbers, avocadoes, garlic, coriander, lime juice and whatever else you think would taste delicious in it.
Fry the onions until soft, add the garlic and fry for another 5 min, then add the ground spices, fry for another five being careful not to burn the spices. Then add the ground round, chipotles and sauce, and water. Turn down the heat and let the ground round absorb all the juices.
Put the tortilla on a plate, top with the ground round mixture, and then if you want cover the little tostadas with cheese and broil them. Serve it with salsa fresca on the side.
The masa harina tortillas fried really give a good flavor. Like corn tortilla chips, only better.
mmm, stomach growling just thinking of it.
