Are vitamin supplements enough to compensate for fruits and vegetables?

I dislike eating most fruits and vegetables because of the crispy texture most of them have. This is a problem for me as I’m trying to gain some muscle definition with regular exercise, and I’m sure I need more vitamins than protein to make progress.

My solution so far has been to drink a bottle of Carnation Instant Breakfast Essentials with a one-a-day vitamin tablet to make up for whatever I need from the greens. However, I’m a bit skeptical about whether or not this is sufficient.
