Green tomato salsa. In Mexico, the two most popular sauces that can accompany just about every dish are salsa roja and salsa verde. There might be only two names for the sauces, but there are hundreds of recipes that vary from stall to stall. Both the red sauce and the green are vibrantly colored and packed full of flavor, and are great on a filled taco or tortilla. Salsa verde was my favorite of all the sauces that I tasted in Mexico City. You can alter the proportions of the ingredients to suit your taste. If green tomatoes are not available, choose the least-ripe tomatoes that you can find, for sourness.
