The main ingredients used are Freeze-Dried Corn, Monterey Jack Cheese and Roast Beef. Let me just say that freeze-dried foods are amazing! They have excellent shelf lives and will give you the ability to have meat, cheese, etc. during an emergency. Simply add some warm water and a few minutes later they are ready to go!
Here's a tip for the Freeze-Dried Roast Beef: Add a little beef bullion and garlic powder to the water when rehydrating for some added flavor.
We made 2 versions of the Grilled Beef Quesadillas the other day. The first basically followed the recipe minus the Cilantro (not very popular in our house). Then we made "Anna's version" using just the roast beef and the cheese.
I'm sure you will enjoy these just as much as we did. Have fun!
