A rice cooker is a great investment. It's, essentially, an electric saucepan.
I'm not a big fan of pre-cut vegetables, but in your case they would be ideal over eating out.
Instead of a recipe, I'll share a concept with you. Using this technique, you can create an almost-endless array of tasty, affordable meals in a rice cooker:
*Disclaimer: I'm not a trained chef, so take to heart any responses that include criticisms or improvements to this process.
Step 1 - "Holy Trinity"
Start with the heat on the high setting, melt the butter and add these ingredients. Once they start to become opaque, add the flour to create the roux. At this time, you can also add other things, such as chopped carrots and mushrooms. Once you've got a thick, gloppy, golden brown concoction, dump it out into a bowl. If you want to step this up, add some sliced smoked sausage or Kielbasa and let it brown before removing.
Step 2 - Protein
You can skip the meat if you have none, or if you don't eat it. This is a great opportunity to utilize meat on the bone. Throw in the remainder of a rotisserie chicken, a ham hock or any pieces of leftovers or inexpensive cuts of meat (such as pork chops or chicken legs/thighs. Fill with enough water (preferably with added stock or a bouillon cube) to just cover most of the meat. (I, personally, try to avoid anything with heavy salt and/or MSG). Simmer this on low until the meat separates from the bone. Remove the meat, leaving the broth, and set it aside to cool. You need to gauge this so that the pot doesn't overflow when all ingredients are added.
Step 3 - Build the Base
Put the Holy Trinity and any additional vegetables back into the broth and increase heat until boiling.
Step 4 - Add Starch Add rice and or canned beans. This is where your concoction becomes "Chicken, and Rice (with or without sausage)", "Black Beans and Rice, with Sausage" "Ham and Bean Soup" or "Veggies and Rice". You get the picture. Boil for a couple of minutes and reduce heat. You may wish to add some seasoning, such as Cajun spices, salt and pepper, herbs, etc. If you want to go with Curry flavoring, throw it in dry, before you start the Holy Trinity (Not sure what the proper terminology is for this; but read up on cooking with curry for details).
Step 5 - Finish Once it has boiled for a bit, reduce the heat to low. While it is boiling, stir occasionally, and pick the meat off of the bones or throw the meat on bone back in. I prefer to pick chicken, because of the small bones that get loose. A hamhock, I'd throw back in, whole. Cover and simmer for 20 minutes. Turn off heat, uncover and let sit for five or ten minutes. Serve up in a bowl and enjoy. You can never go wrong by topping off with a nice dollop of sour cream.
With these basic steps and a bit of imagination, you can cook an endless array of dishes. When you move in with your SO, they will think you are a genius for cooking quick, tasty, affordable meals that make great leftovers for days.
Good Luck & Hope that your situation improves quickly!
