Having picked up a large amount of tomatillos from the market, we wanted to roast them slightly and combine them with crab to serve on a masa flour sope. The crab mixture was seasoned with a little bit of olive oil and small diced hot peppers fro a tickle of heat.
Here's a great post on creating sopes and then loading them up with all sorts of toppings; it's a good guide to making sopes the right way. We cheated a bit on ours and didn't crimp the rims because it really uses alot more oil to fry these little guys and we were trying to make them not heavily fried.
