Call Me Chef Vu

Round 2 of learning/attempting how to cook so I don't starve this upcoming fall. Shredded chicken tacos/mini burritos.. SUCCESS!

I discovered the blessing of a crock pot.. where the work is so minimal I love it. Made enough food to last me a few meals.. even enough to survive my brothers asking for food. But I do how one question, how do people even cut tomatoes so finely. It probably took me like 5min to cut one tomato.. dang son.

Next mission... I will cook.. I have no idea. Any suggestions? (Easy preferably..)
