Here's a good scrammbled tofu recipe that I use often:
extra firm tofu (crummbled by hand), 1 Tablespoon low-sodium soy sauce or liquid aminos, 1 teaspoon garlic powder, 1 teaspoon onion powder, 1/2 teaspoon of cumin, 1/2 teaspoon of paprika, pinch of black pepper, 1/4 cup of nutritional yeast mix together--add in chopped sundried tomato, sliced black olives, frozen spinach, and some crummbled vegan sausage (I use apple spice field roast sausage) if you'd like...
Lately I have been eating oatmeal and adding a tablespoon of peanut butter (Smart Balance brand) when I add the hot water in. It makes very creamy oatmeal and it fills me up and I am not hungry until lunchtime. Next time I am going to add sliced banana to it.
I don't care for most breakfast foods, including oatmeal. On occasion a hot rice cereal with a nut butter or nuts will work for me, but even that is not something I'd eat often. I am also gluten intolerant, so that leaves a lot of things out that don't require much work in the morning. I usually eat whatever was leftover from dinner or some kind of "lunch" for breakfast. I almost always have some kind of bean "salad" in the fridge for quick meals/snacks. We certainly don't have to limit ourselves to "breakfast" foods.
