You certainly don't have to have veggies for breakfast, but sometimes I do. Often I'll do a potato scramble with onions, mushrooms, green peppers, carrots and broccoli sizzle sauted in a skillet and that to simply potatoes, or ore ida o'brien potatoes, cooked without oil (or you can use fresh potatoes). We like to have this on the weekends because it's not a quick fix.
The other thing I sometimes do, just to increase my veggies, is to add shredded zucchini to my morning oatmeal. It doesn't add a whole lot of taste to the oatmeal, but it does increase the nutrient content.
But, truly, don't worry about it if you don't want to have any veggies for breakfast, you really don't have to.
