What are everyone's favorite low energy meals?

Basically just what the title says! What's considered low-energy is different depending on who you ask of course, so for the purpose of this question, just go off what you personally consider to be a low-energy meal.

I've been prowling around for more recipes & ideas to add to my list of "I'm so exhausted and/or in pain I could cry but I really need to eat a real meal" foods, so I thought here would be a good place to ask! I really like making instant ramen cooked in pre-prepared storebought basil & parmesan tomato soup personally. Really tasty & filling while still not making me totally collapse from exhaustion.
