I cut up all sorts of stuff. Fruits, vegetables, cheeses, meats. Seeing as other poster asked about mincing, I guess I also finely dice various herbs and garlic. Sure if I have to smash (mincing?) it I'll find something that can do that with ease, but I won't need a large heavy knife to double-up as a hammer to do so.

An easy go-to meal I guess is like stir-fry with a diced-onion base, which includes a lot of cutting of the above. I've never struggled as long as the serrated knife itself is not super old. They do eventually get dull and the bumps aren't enough for comfortable cutting.
