Or make yourself a large batch of scrambled eggs with cheese, add in bacon/sausage, put it in small containers to grab. In the morning, grab a tortilla and container, and make yourself a breakfast burrito at work. Or make a few omelets or scrambles in the evening to pack up and grab from the fridge.
Do you like cottage cheese? Make up a protein bowl the night before to grab. Cottage cheese, pecans, berries, maybe some honey or a little maple syrup... or go savory with it... add cheese, ham, olives, etc.
