Is there anything wrong eating a lot of vegetables?

And I mean a lot. I just had like half a bag of fiesta style veggies and half a bag of broccoli. The fiesta one was mostly broccoli as well. It was probably about 2 1/2 or 3 cups. I also had about 1/4 cup melted 2% shredded cheese on the brocolli. And I still think I could eat more. I love how I can eat so many veggies and never feel bloated like I can easily get with other foods. So I tend to stick with just eating vegetables with lunch or dinner. I do get protein too! Don't think I skip out entirely on that! haha! I'm also a vegetarian. So my main question: Is it really bad to kind of overeat on veggies?
