Here's my version of fast food.
Cost about $4 (buying the ingredients at Whole Foods). Took 10 minutes to prepare and cook, one cast iron skillet to rinse out, then eat.
Steak seasoned with soy sauce, siriachi sauce, oil, salt and pepper. Red cabbage, a small tomato, a few cloves of garlic. Corn tortillas. Half a lime, flesh and juice.
