I do like cooked carrots and bell pepper so I'm not completely against those. In fact, peppers in general are some of my favorite vegetables as salsa is the one way I truly love raw veggies. I also eat onions raw on salad as well, sparingly, but otherwise cook them. I'm not flat out against raw vegetables, but I don't find many palatable. I've never liked celery or cucumber, unless the cucumber is in pickle form. I don't even enjoy celery cooked, unfortunately. I've always been rather picky. I do like salads when topped with a good vinaigrette type dressing so not all hope is lost and I agree that there are much better types of lettuce out there, but I will pick iceberg over arugula any day.

It's good that you like vegetables as I'm sure it'll pan out well for your body and mind in the long run. I force myself to eat vegetables to be healthier but it would be a lot easier if they were a joy to eat, so I could never begrudge you your joy.
