Bertolli frozen pasta dinners are amazing for a meal that comes completely in one bag. They offer frozen, bagged dinners which are a full meal-meat, pasta, veggies and sauce, as well as just frozen pasta and sauce and in some varieties veggies as well.
They cook up in 10 minutes, and it's pretty hard to mess them up. Use a non-stick skillet and swirl the covered pan around a few times during cooking, to make sure the pasta doesn't stick (and to make you feel like a real cook : ) ).
You could also stock up on fresh vegetables like sweet peppers, onions, broccoli, etc. and make a fritatta. Make sure you buy the veggies right before you need them. When making the fritatta, cut all of the vegetables the same size, to ensure that they cook evenly.
Good extra virgin olive oil and balsamic vinegar are always good to have on hand. You could throw together a quick vinaigrette, and make a salad or marinate some of those fresh veggies mentioned above.
Chicken/beef stock are great to have on hand for making sauces, and your own soups. Onion soup mix is good too. You can use it for the classic sour cream onion dip or make a really quick onion soup with the beef stock and some of those onions I mentioned before.
Rice stays good indefinitely if you keep it in a nice dry place and sealed container. For white rice I love Nishiki brand. This is awesome for good sticky rice. Texmati is a nice brown rice with a little crunch. You could could rice in stock rather than water to add lots of flavor. There are some good flavored rices out there too (box/bag) which will be a bit more "fool-proof" (not calling you a fool).
CousCous is another good, quick side. You can buy flavored couscous, or plain and add your own flavors (I mix butter, roasted garlic-from a jar, and parmesan-you could omit, and when the couscous is cooked, I melt the butter into the tiny pasta and it is incredible).
Hope this provides a good start for you. It's great that your trying to get in the kitchen. If at first you don't succeed, keep at it. Good luck and happy cooking.
