Thanks everyone. OHHHH I am so pleased with myself. Before we left, I cut up some mixed veg - brocoli, snow peas, zuchini and carrots and put them in the fridge. When we got home at 7pm (too late to cook for 3 starving kids!), I threw the kids in the bath, threw the veg in the wok, with a little sweet chilli sauce, cumin and corriander, and by 7.15pm we were eating. And I had 2 really little pieces of ham and p'apple pizza, with my yummy stir fryed veg. And I am really full and not feeling stodgy like I would if I had eaten the whole pizza (which I have been known to do!)
So I have proven to myself that I can do it, and I am so satisfied and not hungry. And actually I sort of enjoyed the veg more than the pizza
Now where did THAT come from? Cheers everyone.
