Nothing rounds out a taco party like a bowl of fresh pico de gallo. We make ours with fresh plum tomatoes, but you can use any good looking summer tomatoes you can find. Most salsas like this one don't call for any oil but we added a couple of tablespoons to even out the bright flavors of the tomatoes, salt, and lime, and help it stick to your chip. A pinch of cayenne adds a little mystery heat, but feel free to leave it out. Seed the jalapeo for a milder batch, but don't skip it: its floral flavor is what turns a bowl of chopped tomatoes into an addictive dip.
