Today I had homemade multi-grain bread fried in butter. For some reason, it really hit the spot.
Some mornings, I just nibble on cheese (sometimes cheese spread with Vegemite) or feta.
Eating cottage cheese straight out of the carton, salted, is an option too. Sadly I went from loving that to loathing it in the space of a few spoonfuls...
I mgiht try the PB sandwich tomorrow. I'd forgotten that PB = protein!
ETA: Ooh. Hummus? Hummus mixed with yoghurt is good. You could have it with crudites or crackers or just bits of bland toast, if that's all you could stomach.
