This is the best spinach dip I've ever eaten! I do not like onions in mine because I can't stand to hear and feel the crunch on my teeth. Got this from kellyskornerblog (well, her recipe blog)
1 box of frozen spinach
1 8 oz. pkg of Monterrey Jack shredded cheese
1 8 oz. pkg of cream cheese
6 T. Parmesean cheese
1 can of rotel
Cook spinach in microwave, drain well. Combine all ingredients and heat until cheeses melt. Stir well.
It is wonderful. I made it for our inservice/work day at school yesterday and we ate all of it.
