I'm a vegetarian, but also eat no breakfast (unless you consider espresso with a little skim milk food), pig out for lunch on rice & beans, lettuce & tomato salad and ripe plantain, with a plain vegetarian burger patty (my favorite two being Gardenburger Flame Grilled and Boca Burger Flame Grilled - same product name, very different implementation).
For dinner I eat another veggie burger patty and a shake made with 4 oz Mango Orange juice, 4 oz organic skim milk, Plain Metabolol 2 protein powder (product of Champion Perfection), one frozen banana and 5-6 frozen organic strawberries or a gagle of frozen organic blueberries, mixed in a Hamilton Beach Commercial milk shake blender (the frozen banana & strawberries get a bit of a micro-nuke to make them blendable).
I'll have a snack of two banana waffles, two blueberry pancakes or a Skinny Cow low fat ice cream sandwich. And there's the afternoon espresso drink of course, same as the morning. I roast my own coffee.
I eat the same thing every day, really enjoy it, never get tired of it. Once a week or two I'll go to a spicy Indian buffet or have some spicy Mexican cheese enchiladas or huevos rancheros ...
