A good example for upf that is not likely to be bad for you is (European style) frozen pizzas.
And I think your comment is wrong. Parent is right in saying that there is no clear definition of what exactly ultra processed food is. However, in general, processed does not mean having additives, it means processed, running through multiple industrial processes to be made.

The definition of upf is 'food having additive of no culinary or nutritional value'. That's the current definition.
The original nova definition is 'food with additive of no culinary value', which isn't useful for nutritionists, hence it evolved.
I seriously doubt all frozen pizza are upf, the main advantage of frozen food is that you don't have to add nitrite salt or other conservatives. Maybe in some pizzas, to keep colours bright?
