Given the chance, I would have a bagel, toasted, with butter almost every day for breakfast. Every so often I'd switch it up and go with waffles, or pancakes, or French toast. Bacon is another great breakfast food! Donuts and cinnamon rolls, also good. Basically, if it's carb-y and/or sugar-y, I would love to eat it for breakfast! I hate eggs though, so no eggs for me.
My reality is usually a cup of cherry yogurt, and either some apple slices or mandarin oranges. Before I started trying to lose weight, I would normally eat a buttered english muffin and a couple slices of bacon for breakfast. It's delicious, but the idea of all the fat kind of made my dietician cringe, so I'm trying to not eat that very much anymore.
