Help ...

What is a good cheap dinner option that I don’t have to spend money on at the grocery store like crazy I want to do something like soup or sandwiches for the next week or two so I don’t have to spend a lot of money what else could I do I’m just tired of eating out. And also what else could I do my bf got a new job and will be home during the day so what could I get for him to eat on for breakfast ? I literally want to loose weight as it is but also don’t want to spend a ton of money. I’m not picky I could eat soup for a week . I’m just worried about my bf. He doesn’t like certain things and likes eating out.
