To start, make the filling. This can be done a few days ahead of time and refrigerated. Bring to room temperature before using and warm on the microwave or stovetop. Alternatively, the meat can be cooked and frozen. If you are freezing the filling, be sure to allow it come to room temperature before freezing, To use, thaw overnight in the refrigerator and bring to room temperature before using and warm on the microwave or stovetop.
Heat one tablespoon of oil in a saucepan on medium heat. Add the ground beef, turn up the heat on medium-high and break up the meat as it cooks. Make sure that the meat is completely brown before adding the seasoning. Add the seasoning and stir well. Add a little water to moisten. Put on the lid and turn the heat to low. Allow the meat to cook further for about 10 minutes. The turn off the heat.
In terms of ingredients to make the quesadillas, feel free to use your imagination. Here is one suggestion: red peppers, black beans, corn, cilantro, and cheese. You will need about one half cup of each ingredient for about quesadillas. I like to use small glass bowls for each ingredient. Being organized will help the whole process go smoother. For the red bell peppers, I prefer to use fresh peppers cut in small dice. For the black beans, use the canned version. Put in a small colander and rinse with cool water. Likewise, for the corn, use the canned version and drain out the water. Finely chop the cilantro, leaves and stems, to yield about two tablespoons. For the cheese, I use sharp cheddar simply because it's usually what I have on hand and has a nice robust flavor. You can also use authentic Mexican or Mexican blend.
Heat one tablespoon of oil in a medium saucepan on medium heat. Place a flour tortilla on the pan. Put about 2 tablespoons of the meat mixture on one half of the tortilla. Sprinkle shredded cheese, chopped red pepper, black beans, corn and sprinkle with chopped cilantro. These are approximate amounts but feel free to adjust the amounts to your preference. Turn down the heat to medium low.
When the bottom of the tortilla has turned a light golden brown and is starting to crisp, use a wide spatula to gently lift the side that does not have any of the filling. Fold it onto the other side. This will make a half circle. Continue to cook on low until the cheese is melted.
Remove the quesadilla to a wooden board and cut into wedges if desired. Otherwise remove directly to a plate. Serve with sour cream or lime crema.
Garnish with cilantro, lime, sour cream and salsa.
