When I was young, my parents were always looking for ways to get my sister and me to eat our veggies, and the method that worked the best was disguise!
My mother would cook up some frozen mixed veggies, and there would always be lots left over because we couldn't stand the lima beans. So the next night we would have meatloaf with the last night's veggies mixed in, and lots of ketchup on top. We loved it!
My suggestion would be to put a few veggies into saucy things, including spaghetti sauce, stir fries, soups, etc. Start out with just a little, but try to make it consistent. Even grating a carrot into soup or spaghetti sauce counts as a veggie. Start out slow, trying out different things to see which ones you either like or at least don't mind. The tomato paste in spaghetti sauce counts as a veggie. Throw a little bit of lentils into a soup.
I'm not particularly enchanted by salads, just like you. My husband loves them. When I do make them, I try to put a variety of veggies in, like grated carrots, bell peppers, mushrooms, cucumber. The sweetness of corn would make all the rest taste better, in my opinion. The important thing is that you find some things that you don't mind eating, and you might surprise yourself by finding a few that you actually like.
As an adult, I sneak lots of veggies into my meals, and dutifully steam brocolli or green beans to serve on the side. The veggies are, to tell the truth, not my favorite parts of the meal, but I've been doing it so long (especially the hidden veggies) that I'm used to it, and I eat the steamed veggies first and then enjoy the hidden veggies with the more flavorful things.
And as for fruit, I put a banana into my cereal in the morning, and forget other fruits the rest of the day. The nutritional guidelines are a goal, but if you're trying SOMETHING in the fruit and veg direction, then you're doing good. Start out slow and see what works for you.
