Jillybean:
I am sending you a huge cyber hug, from one who also wasted too much of her life in her twenties trying to control her eating and missed out on so much pleasure and health. Make a return to vegetables a pleasure trip. There is life beyond potatoes and corn.....
Take a grocery basket and go cruise the aisles of a really good supermarket. Look at the variety of shapes,colours, textures that are on offer there and let your mind wander around the possibilities. Buy an excellent Vegetarian cookboook: I have the Green's restaurant book by Deborah Madison, and let your eye roam. What takes your fancy? Rather than thinking of specific vegetables that are on or off a hit list, think "what is in season and what different ways could I cook it?"
Brocoli is so over done as a vegetable I never eat it any more. Asparagus is on sale in my shop right now and so I am going to try drizzling them with a little olive oil, a variety of chopped fresh herbs, some blanched almonds and microwave them for 4 minutes and see what I end up with. I adore collards or greens of any type just steamed lightly and eaten immediately with a light touch of salt.
Soups are wonderful things for making vegetables a part of your diet in an extremely palatable way, and they absorb the juices of the cooking process so wonderfully, they are revolutionized. One of my favourites from the Greens Book ues a curried stock base that you make yourself and one of the best parts is making it from scratch on a lazy Sunday afternoon, because the aromas waft around the kitchen and you just can't wait to eat that soup!
Red peppers: high on antioxidants and such a deep hue. I buy as many as I can and throw them into any dish possible in abundance. Think:salsa! Think: guacamole with avocado pears (basically two mixed with Worcestershire sauce, yoghurt, black pepper, a couple of tomatoes all blended or with chunks of tomato for texture--takes 5 minutes to prepare and often in my house becomes the dinner for the evening) and eat with crudites, strips of peppers, pieces of celery, baby sweet carrots, whatever. Just forget the broccoli. There's no reason why you should ever have to eat that vegetable again!!!
Think also: loads of red and orange peppers folded into a fluffy two egg, french style omelette or into a quiche.... Pipperade?
Experiment with vegetable and herb combinations so you think in terms of dishes, rather than, I must get my 5 servings a day in which stresses me out to think of!
Fruit can be easier to adapt to rather than vegetables. Cantaloupe, strawberries and blueberries have more nutritional weight than any other fruit going. High on antioxidants. And when Summer starts, there will be melon, nectarines, cherries, peaches and you probably won't have time to even think about eating brocoli or grapefruit!
Jellybean, try to let go of anxieties and let yourself experiment. Once a week, make a vow to try out some new receipe, some new ingredient or style of cooking. Indian food is some of the most wonderful on the planet. See Madhur Jaffrey cook books.
My thoughts go with you and I hope some of this helps
