Here's another variation.

After I sprayed the pan w/ oil, I roasted 3 cups of cauliflower in the pan for about 35 minutes (they turned from white to a light golden color.) I then added the 2 cups of cheese & egg base on top of the roasted cauliflower and proceeded w/ the recipe as written.

With the added veggie, the base came out much more substantial than usual. I found that one serving satisfied me and I easily resisted that 2nd serving. It reheated nicely the next day.

(Oh, I topped with beef link sausage [sliced 1/4" thin], mushrooms, and jalapenos [all sauteed together] and, of course, spicy pepperoni & cheese.)
