Aim for 5 servings of veggies a day. This isn't as tough as it sounds-an entree salad could be 4 servings right off the bat.
Some nutrients are lost in cooking, particularly water soluble vitamins in steaming. Some nutrients aren't "unlocked" until a food has been cooked, like lycopene in tomatoes. Some nutrients are much better absorbed by your body in conjunction with other nutrients, like iron and vitamin C. Some vitamins are fat soluble and require fat to be absorbed. For these reasons, I really recommend eating whole, traditional type foods and food pairings. Tomato sauce with olive oil, corn tortillas with lime, beans and grain, etc. Try to eat foods that are in season-in the winter, it's greens and root veggies. These really need to be cooked, so you'll do more cooked veggies. In the summer, it's cucumbers, baby greens, snap peas, sprouts, etc that are much better raw.
You want a variety of color and the deeper the color, the better. If you're doing 5 servings a day, aim for 3 of them to be dark leafy greens (broccoli, spinach, lettuces, kale, chard, etc) and the other two to vary. Maybe an yellow bell pepper and some mushrooms today and carrots and eggplant tomorrow.
If you can, do a starchy veggie in addition to the other 5 to round out a meal instead of grain.
Beth is correct-liquor without a mixer is your best bet for drinking socially. Or club soda/seltzer. Though it might be more pleasant to enjoy one glass of wine with some cheese and nuts...
