Kids, as well as adults, love these simple but tasty snacks. This is a great after school snack. When my son (then my granddaughter) was small, I would keep a batch of the topping made up in the fridge, along with an extra loaf of party bread. This way I could give them a nice snack to tie them over until dinnertime. I would also serve this when they had playmates over. Oh, I was the coolest mom (then Nana) ever!!!
Mix first 5 ingredients until well blended. Spread mixture, probably a tablespoonfull, onto slices of party bread. Bake @ 350-375 until cheese has melted. Serve warm...be careful not to overbake. Note: topping can be stored in fridge (up to 4 days) until ready to cook. You can use any party bread you desire. I'm sure it would be good on french bread or bagles, too.
Note: Sometimes I add slices of pepperoni on top as well. I also add parsley or green onions to the mixture. This, of course, is optional.
