Yes, follow John's advice. Degrease the pepperoni by putting it on paper towels in the microwave. You will be surprised at the amount of grease on the paper towels afterwards. Suggest 15 to 25 seconds, but you'll have to experiment with your particular microwave and also how much you want to dry it. That usually solves the common "greasy" pepperoni pizza problem (altho there are many in this world who like greasy pepperoni pizza!). My guests like me to "nuke" some more pepperoni till its crispy and then eat it as is as a snack apart from the pizza! It actually is very good that way.
An alternate suggestion to putting the pepperoni under
the sauce is to wait until the pizza is nearly cooked and then putting the slightly microwaved pepperoni on top
instead of under the sauce and cook for a few minutes more afterwards. I started to do that recently with good results.
Many of us of the male species here on this site understand the dilemma of having the wife that likes her pizza a little differently. It's hard to re-train them, eh? But there's always ways to find a compromise (e.g. 2 small pizzas?? One can get pans as small as 6"). Just kidding (my wife may be watching).
For deep dish pizzas only (but not thin crusts), I drain the 6 in 1 and Glen Muir diced tomatoes for about 15 to 30 minutes max. I don't like them too dry, but that may be a matter of personal preference also. Good luck with your next pizza. --BTB
