i need some suggestions of what i can make for packing lunch box... considering it's going to be hot food, not rice + "食送" that type... can be reheated...

so far what i've already made is spaghetti, fried rice, fried udon... any other suggestions?? (p.s. i'm very beginner in terms of cooking so pls give me easier suggestions thanks >__<)
