One of the easiest Mexicans recipes for breakfast or even dinner is Chorizo con papas only for breakfast you would add egg, and dinner would be just chorizo con papas. Ingredients you need for this recipe is: Mexican Chorizo(spicy/mild), potatoes(Idaho preferably) is the ones I use!, eggs, and any other spices you would like to add. (I personally add salt pepper and garlic and herbs spice), and parsley.
Tacos or burritos
My obvious favorite is going to be tacos, but my kids love when I make mini burritos for them and wrap them up for them since they have little fingers, so if u have little fingers or depending on your preference you decide if it's going to be tacos or burritos for you. Either way both are Delicious!:P
