Extraordinary Cheese Dip

I know that we've made this, most of us have tasted it, some of us have tasted it at 3:30 in the morning because we couldn't resist its siren call. I keep losing the pieces of paper that I have it written on and I can only ask Erin for another copy so many times before I start to feel like a complete knob.

250 g spreadable cream cheese
1/2 c grated cheddar
1/2 c grated mozzarella
1 c mayo
1 t VE Cheese, Chives & Bacon dip mix
1 t VE Lemon Dilly dip mix
1 t VE 3 Onion dip mix
1 or 2 rounds of sourdough bread (or see the Wheat Snackers recommendation from March)

Combine all of the dip stuff until well blended. You can bake it at 350F for about 20 minutes or so in the sourdough loaf but I just use an ungreased casserole dish. I'm thinking of trying a mold to see if it will hold its shape next time because that would be really cool to see.
