Prepare Tortillas for taco making. Wheather using already formed shells, or shells you will form after cooking, heat before assembly

The fun part is assembling as you want. I always have more corn tortillas than I need so I cut the extras and make tortillas

OPTIONAL:

Change up olives with calamatta

Have salsa and sour cream
