First I chopped up some red onion, cilantro, red pepper, crushed red chili, and basil. I mixed that with some lime juice and a little olive oil. I boiled some Trader Joe's frozen shrimp in water and lemon juice, mixed it up with the ingredients, squeezed a lemon over it, and let it chill in the fridge for about an hour.
I put the mixture over a plate of mixed greens. I was very pleased with the results. If I make this again, though, I'm going to mince a couple jalapenos and throw them in - I think that would have gone well with the acidity of the citrus.
