🟥小腹が空く🟥

Most simply we could say that, "I'm just a little hungry," to mention we have a small amount of hunger. "I could eat," is something we say when we don't feel hungry or the need to eat, but we wouldn't be against the idea of having a snack. "Peckish," means that we could also be interested in having a snack.
