I'm addicted to sourdough rye toast with Yumi's brand hommous, sliced ripe tomatoes, a dash of olive oil and pepper. Yummo!
prior to pregnancy, I'd make Bircher muesli with a good untoasted sugarfree muesli with extra rolled barley added , soaked in a high quality low g i fruit juice with homemade (easy yo) yoghurt.
Kept me going for hours and was easy to make in individual containers so I could grab one to eat on the way to work.
