[Request] Recipes that can be eaten cold

Hello guys,

First, some background information: I'm a commuting college student. So the day before I would prepare food (lunch and dinner). The thing is that my classes are packed and I barely have time to run to the closest microwave to warm my food. So I often eat my food cold. I'm VNese so my lunch and dinner always include rice and some sort of meat and veggie. However the rice often gets soggy and cold when it comes around dinner, still edible but usually kill my appetite.

So I am looking for recipes that that can be eaten cold or without the help of microwave.

Thank you and happy cooking!
