Season the beef with dried oregano, granulated or powdered garlic, S&P, grated parmesan (can is OK), and a pinch of red pepper flakes.
Personally, I prefer the ground beef to pork sausage on a pizza.
Much as I love Velveeta Cheese, (and yes, I have used it for pizza when that's all I had, and my kids loved it), use at least some grated mozzarella! If you buy a chunk of the store brand and grate it yourself, it will be just as cheap as the Velveeta.
