I take frozen pizza that you're supposed to bake and either put it in the microwave or on a stovetop. I don't have an oven.
Am I going to get sick?
Everything on a pizza- albeit not the pizza itself- had to be precooked in virtually every imaginable scenario unless you had a really weird topping, so you should be fine.
That having been said, the texture probably leaves a lot to be desired.
My go-to brand says on the package to fully cook before consuming.
Not entirely sure why.
Why buy frozen pizza without having an oven?
OP. Order one of these. I don't have an oven either so I use this. also does cookies, and biscuits. http://www.amazon.com/Presto-03430-Pizzazz-Plus-Rotating/dp/B00005IBXJ
Never get drunk around one of these. I punched my friend in the face and when he tried to brace his fall his arm landed on that grid plate. We had just cooked a pizza so it was hot and burned its pattern in his arm. Sweet looking scar I gotta say.
