Great salsa -- "medium" is a perfect balance of spiciness and flavor. Unopened jars can be stored & will stay fresh in your kitchen cabinet for anywhere from a few months to a year (see "best if used by" date). Once opened, you can keep the remaining salsa in the fridge for about a week or so... but it never lasts that long, in my house. Tostitos Salsa (served with Tostitos brand tortilla chips) is an ideal snack option for tailgate parties, or to prepare for last-minute guests. It's always a surefire crowd-pleaser. Best of all it's relatively guilt-free. One 2 tbsp serving is a mere 10 (that's TEN) calories and 0 (yes, ZERO) grams of fat!
