Here's an easy recipe for hot spinach dip (when I say hot, I mean not the cold version made with Knorr's soup mix. This is the kind served in restaurants like Houstons and TGI Fridays)
2 cups shredded mozzarella cheese
1 1/2 cups shredded parmesan cheese
4 oz. cream cheese
2 cups heavy whipping cream
5 tbs. mayonnaise
1 lb. chopped spinach (I buy the frozen and defrost it in the microwave)
salt and pepper to taste
Mix all ingredients over low heat, stirring until cheese melts.
I serve mine in a crockpot on low. You can add a small can of artichoke hearts if so desired, DH doesn't like them so I leave it out.
I serve it with tortilla chips, salsa, and sour cream. I like to mix the salsa and sour cream in mine...it adds a bit of zest to it.
