Mom's Salsa is the best--for a really quick salsa.
You have to be thinking ahead though, because it tastes so much better the day after it's made...and the day after that, and the day after that, and especially the day after that. :o)
1 can fire roasted diced toms
1-2 cloves garlic (i always add more cause i was Italian in a former life)
1 small can diced green chilis
crushed red pepper flakes to your taste
1/2 small onion, diced finely
Mix these up the night before tacos, nachos, or your next guacamole craving and you'll be good to go.
If you like salsa a little less chunky, you can whir it up a bit with your whirring instrument of choice.
