Our kids love frozen pizza, so when General Mills recalled 3.3 million Jeno's and Totino's pizzas, we were scared.

Those cold spots allow bacteria to survive." Cooking food in an oven is definitely safer. But for those of us who just don't have the time, here are some tips from the FDA on making microwave cooking safer.
