Go back to your favorite breakfast!
Just substitute steel cut oats for the oats that you are using.
Other ideas for breakfast... I like making a smoothie in the morning. I have tried various smoothie recipes, but there aren't too many that work for me, so I had to work on tinkering with my recipe, finally got a blend that works pretty well. I blend in 1 cup frozen strawberries, 1/2 cup plain fat free yogurt, 1/4 cup cottage cheese, 2 tsp olive oil, 1 block's worth of plain or vanilla protein powder, and I also add my fish oil to this smoothie. If I am out of protein powder, then I just add more cottage cheese.
Also , have you tried hummus deviled eggs? I personally don't care for all of the work that goes into these (I don't like peeling eggs), but they are surprisingly filling. Boil up 6 eggs, then peel and cut in half lengthwise. Scoop out the yolk and replace with your favorite flavored hummus (or be creative and make your own).
