First off: grilled cheese, scrambled eggs, and pancakes are "alternatives" ?!?! Add in organic whole-wheat nuggets and the like, and that's what we've been living on since I started back in school!!! It was just pancake night last night!
Secondly: Major empathy for trying to finish up law school as a single mama! I've just been taking some additional classes and have been knocked on the head with how grateful I should be that when I was in law school I could just hide away with my books until things were done. And that I could stay up until 3:am finishing something because there wouldn't be someone waking up at 5:30 ready to go for the day! I'm only taking a couple of classes but it's on top of working full time and it kind of sucks! A lot! Seriously reconsidering this plan for a variety of reasons, but one of them is that I miss just hanging out with my son! When we were at my mom's this summer, she was playing with him while I took a test, and he was happy for a while, then sent her away "Grandma, I'm going to build dinosaurs. You go work on your computer."
And finally, it's a hard gig finding work after graduation! If you can move, it might be worth checking out some less obvious career options. I've worked for a giganto corporation for the past 6-ish years that hires TONS of lawyers-who-don't-want-to-be-lawyers. And some who just need a job! HINT: look up the main websites for any company that provides you with a research password while you're in school. Usually at the bottom of that page will be a link to "careers". I didn't get in until a couple of years out of school, and the competition is tough, but I did get in. Not a dream job, but mellow and good for someone with a family (no overtime!).
