Hey Blackstripes, you sound like a young chick!
When I left home at 19, I couldn't cook worth a darn - even though I did help out in the kitchen. I could bake cookies and stuff, but planning and preparing a meal was totally alien to me.
However!!! It costs SO much to eat out all the time I just had to teach myself. Here's some tips for you (other than living on Lean Cuisines which gets old very quickly - high in sodium besides).
*Invest in a George Foreman Grill - they come in all sizes. I have the small Champ model that I bought at Target two years ago for $25 which is just the right size for a one or two person household. Not only does it use very little energy (here in California, we have to keep that under consideration these days!) but it's a snap to use, comes with a book of recipes - and don't forget that the fat runs right off! Also great for veggies.
Here's a simple George Foreman grill recipe:
Buy a bag of those frozen boneless chicken breasts (those are so handy). In the morning, before you leave for work or school or whereever, take one or two out of the freezer and pop 'em in a Ziploc bag with some marinade (buy it or make your own with soy sauce, white wine, lemon juice, salad dressing - whatever sounds like a good marinade ingredient) and a dash of pepper. Put the Ziploc bag in the fridge to thaw out during the day. When you're ready to eat, just turn on the ol' GF grill, take the chicken out, put on the grill and close the lid - takes about five minutes if the chicken is thawed (sometimes I just put the frozen chicken right on the grill - takes longer but still comes out good!). You can also use the grill for steak, fish, Gardenburgers, whatever.
Now - side dish. You need your greens, so get one of those bags of prewashed salad mix, throw a sliced up Roma tomato in there - maybe some Garbanzo beans - or how about Craisins (dried cranberries)? Whatever suits your fancy. Top with your favorite salad dressing and toss until blended. TIP to use less salad dressing - instead of putting the dressing ON the salad, have it on the side in a little dish and dip your fork in the dressing before you spear some salad. You'll use less dressing and still get the flavor! Another way of using less dressing is to toss your salad and dressing together in a Ziploc bag rather than using salad spoons - the dressing will be better distributed throughout the veggies.
One of my favorite basic side dishes is Brown Minute Rice (not the white - more nutrients and fiber in the brown!). Easy and fast to do. They usually put some really easy recipes on the side of the box as well. An easy and quick one is mixing the rice with some black beans and salsa, heat and eat with whole wheat tortillas (I recommend La Tortilla's Low-Carb whole wheat tortillas - only 60 calories each, lots of fiber and protein!).
Keep a lot of stuff in the fridge that's easy to prepare and ready when you have the urge to nibble - washed and cut fruit; baby carrots; low-fat cottage cheese; fat-free, sugar-free yogurts; Diet Cokes; etc.
Check your local rec center to see if they are offering a class in easy cooking for adults (you'd be surprised!). I took an awesome beginner's sushi class a couple of years ago at our Rec.
Find easy, low-cal recipes and try to make something new once every couple of weeks.
One of my favorite low-fat cookbooks is "Looneyspoons". Good recipes - most are fairly easy - and fun to read.
Bottom line is - no one is born with a 'chef's gene' - cooking is an acquired skill that anyone can learn! Good luck!
