Back in the 80s, in Michigan, in almost every grocery store, in the frozen section, there were frozen pizzas that came 2 or 3 in a stack. They had a little white label, they weren't any of the major brands, they weren't even very good. Just 2 or 3 frozen pizzas on a cardboard disk, shrink wrapped. They only ever had 2 or 3 varieties... Cheese, or pepperoni (it was always the little cubed pepperoni), and I think they had a "combo" that was pepperoni sausage and green peppers. I don't know who made them. I don't think it was one company - I think there were different companies that all put out their own version, but they were all pretty much the same. Two or three medium-ish size pizzas, stacked on top of each other, on a cardboard disk.
And they weren't great.
But I wish I could still find them. I get so nostalgic for them sometimes. Me and my dad used to get them sometimes when mom was away. Sometimes we would put stuff on them, shred some cheddar cheese, or open a can of canned mushrooms, or something.
Again: Not good pizzas. I just miss the memories.
