The folks from Red Baron parachuted in last week with an assortment of new products that should be appearing in your local freezer section soon. Perhaps the one that interested me the most was their By the Slice microwaveable pizza. I mean, look at the box. It says "By the SLICE" on it, with the emphasis on SLICE, as if they were trying to get my attention. It's billed as "the first microwaveable slice of pizza that provides unbelievable pizza taste from the microwave." "Unbelievable," huh? That sounds like a challenge, so I figured I'd put the stuff through its paces in a Reality Check.
