I know exactly what you mean. Not only can I not possibly keep up with cleaning my house, but it's also pretty tough to come up with quick meals (and don't you just hate to cook on clinical days? I do!)
What I have found works best for me is to get a big bulk package (like 5 or 6 pounds) of ground chuck and brown it all in a big batch, then package it up in individual freezer bags. That way, when I want to cook I can just grab a bag out of the freezer and it's ready in like a minute on defrost (or if you're really ahead of the game you can stick the bag in the fridge before you leave for the day). I buy ground chuck a lot because it's pretty cheap and let's face it, I'm on a nursing student's budget
I will splurge on boneless skinless chicken breasts though. They are really handy and can be used for several purposes.
As far as recipes, a couple of quick things I do are as follows:
Take noodles of your choice (boiled and drained) and add a jar of spaghetti sauce.
Add a bag of ground chuck (conveniently pre-packaged) and mix well. Bake it at 350 for about 20 minutes. Top with cheese (mozzerella or cheddar work well) and bake for 5-10 more minutes.
In a medium sized crockpot (I love crockpots) add one bag of ground chuck, some minced onion, 2-3 cans of Veg-all (hey, it's quick), a can of Rotel diced tomatoes and green chilis, a can of black eyed peas, a can of corn. I usually toss a couple of beef boullion cubes in there too. Add a little salt and pepper and cook on low overnight or start in the morning and it's ready by dinner. The only effort involved is opening your baggy of meat and opening a few cans. (Tastes yummy with some sliced french bread, too.)
A quick beef stroganoff is to brown one pound of ground chuck in a large skillet, draining well. Add one can cream of mushroom soup and one package of Lipton Onion soup mix and a couple of tbsps of worschesteir (sp?) sauce and simmer for about 10 minutes. While this is simmering cook one package of egg noodles, then drain well. Add half a cup of sour cream to your beef stroganoff mixture and mix well. Serve stroganoff over the noodles and enjoy!
These are just a couple of things I do. Hope it helps and good luck with the rest of your semester!!
