What do you mean, "There's no shrimp"?!

So. What do you do when you've planned a meal around a nonexistent shellfish? Completely change course, while still using the fine, fine local summer squash & green pepper, that jalapeno you found but can't remember why you bought, cumin seeds, & of course some onion & cheese. Serve with that homemade tomatillo-chipotle salsa that was found hanging out in the back of the fridge.
