Eat what you have. It doesn't have to 'match' to give you nutrition and make you full. :)
You have to do what you can...
I've made veggie soup and put curry paste in it to season it up and it was tasty. If that's all you got then make it.
eating only peas and broth for one meal isn't gonna hurt ya.
Check with your local church. A lot of them have food banks.
Do you have any chicken?
