I will never say that! You cannot put too many goodies on a pizza, IMHO. We like any or all of the following: sliced salami, sliced or cubed pepperoni, browned Italian sausage, sliced black olives, diced onion, diced bell peppers of whatever color is on hand, thinly-sliced Serranos, artichoke hearts, pesto and pizza sauce. The only things I'm NOT real fond of on pizzas is ham/Canadian bacon and pineapple. Otherwise the sky's the limit!
We'll be making one tonight but I'll be using a low-carb flatbread as a base, then topped with a good schmear of pesto, then some Trader Joe's 3 cheese marinara sauce; then browned Italian sausage, cubed pepperoni, sliced salami, sliced black olives, artichoke hearts, peppers, onions, and plenty of cheese. I like anchovies on mine too and if I can remember will put them on half, as KOTC doesn't like them. I can't wait.
