Adapted this from Kraft Food & Family magazine. So simple and quick, but completely delicious! You can make it as hot as you want by changing up what kind of salsa you use. I also like to add a little lime juice, unless I am using the lime salsa. If you can't find the 4 cheese blend, you can use a mixture of cheddar and monterey jack (or pepperjack, for an extra little kick!) Serve with tortilla chips!
