I haven't made these in ages, and I had forgotten how good they are! All I could find at the store today was garlic cheese in the 6 oz tube, so I used 5 oz of that, and I subbed butter for the margarine. Before broiling them, I baked for about 5 minutes in a 425 oven on the lowest rack, just to crisp up the bottom. I think it would be even better with the sharp cheese as stated in the recipe, but we couldn't stop eating them!
