I call foods like bell pepper, tomatoes, cucumbers, etc. vegetable fruits or non-sweet fruits. Yes, botanically they are fruits, but they have a nutritional make-up closer to vegetables and so are less sweet and lower in calories than sweet fruits.
i think you'll be fine with nutritional balance if you eat a good variety. i count tomatoes, zucchini, cucumber, and carrots as my "veggies" for the day even if they are fruits. i don't think the label really matters.
I agree with swayze and joannabanana--- but, I do suggest throwing in those leafy greens if you aren't eating any. They are highly beneficial. I don't eat them every single day, but I try to get them in a few times a week at least; I have noticed a difference from when I'm not eating enough leafy greens vs. eating them a few times a week. I feel a lot more lethargic and my digestion doesn't perform was well when I'm not consuming leafy greens.
Leafy greens that I suggest: kale, romaine lettuce or red leaf lettuce (my favorite), broccoli, spinach
These are what I like to eat anyway :) Mostly spinach and lettuces for me.
