Red Baron is ass. Keep in a decent pizza like Freshetta. THAW IT FIRST.
Then
peel off as much as you can and reconstruct the pizza from sauce up,
adding more [and more!] cheese, plus whatever meats, fresh veggies
[onion!] you have about.
Now you have a pizza!
If
you have a pizza stone or cookie sheet, good. With all the ingredients
at room temp, we're emulating a pizza parlor. Fire up your oven to MAX.
It won't be 900 degrees but let's shoot for 525.
I like a little olive oil on the crust rim before and after. Then rock! Trust me on this one.
