I'm pretty basic when it comes to breakfast (and egg sammie on wheat bread always does the trick for me). However, if I don't have eggs or not in the mood to cook, I try to incorporate healthy (as healthy as possible) cereal w/ a banana. I prefer my cereal w/ oat milk as well. It has a good balance of "enough" for me to get me through to lunch time. Plus, I'm not a muffin/bready food guy, nor am I a huge fan of protein bars or shakes (told you I was basic LOL). So this is a good halfway point for me that I'll actually eat.
Though, on my mornings where I have time to cook, eggs (1 or 2 eggs + 2 egg whites) and home fries (regular or sweet potato for a complex carb) is my go-to!
Oats, sandwiches, boiled eggs and milkshakes (breakfast recipes).
