A hot dog bun is just a holder for a filling. My mom used to sent tuna sandwiches to school in hot dog buns, because they got a lot less soggy than regular bread.
Sometimes it's hard to think outside the box on food and how to use it. I once drove a roommate nuts because I'd put tomato sauce on rice instead of pasta. Well, I had the rice and I had no pasta and it tasted good, so why not?
My biggest food waste is when I cook a meal, and then am not hungry enough to eat it all at once. I'm fine with cooking a big batch of something, planning to freeze it in individual portions. But when it's actual leftovers, they tend to get put in the fridge and forgotten. And because I usually plan out my meals for a week or so at a time, there's no logical meal to include them in. I need to work on this.
