Heat oil in a hot pan and sauté the ground beef. Season well with spices, chopped chipotle peppers, salt, pepper, and a pinch of sugar.
Add a little water and let it simmer for about 10 minutes until the meat is tender and juicy.
Place grated cheese on a soft tortilla and microwave for about 20 seconds until the cheese melts.
Sandwich a hard taco shell between the melted cheese layer and the soft tortilla. The cheese acts as a glue to keep the shell crispy and prevent the taco from falling apart.
