What kind of salsa do you like? I see your location is in New England, so your idea of an awesome salsa recipe might be different from mine.

This is my usual go-to salsa recipe, which is very much like what you'd find in a a typical Tex-Mex restaurant where I live.
1 large can whole tomatoes (with the liquid)
1/4 large white or yellow onion
1 jalapeno or serrano chili (more or less to desired level of spice)
1 handful fresh cilantro
salt
pepper
1 clove fresh garlic
a little cumin
juice of 1 lime
whiz in blender until thin/thick as you like
