Could you recommend some high protein breakfasts, not including yogurt or omelettes (omelettes are time consuming)?

Halloumi sandwich:
Grill the halloumi
Spread tomato purée on either side of the buns and put them in the grill for 2-4 mins to heat them up
I like to put Nando’s medium hot sauce on the bun as well as mayo but that’s preference just assemble the sandwich and it bangs
