See if your local megamart has one day a week when they’re cheaper, especially. Even better is Costco if you know someone with a membership. Heck, may as well get a Costco hot dog while you’re there.
If you are up for cooking, look for whatever chicken parts are on sale each week or two.
Cook farro instead of rice, it’s chewy and nutty and has protein and fiber
Eat lentils
Bean, farro and cheese burrito - add some of that rotisserie chicken too
I’m really sorry for what you’re going through 💛
