Last school year I usually had a quick bowl of oatmeal during my planning period, which was the first block of the day. This year, my planning will be right before lunch. I'm never hungry enough before leaving work for breakfast, but come 10:00, I'm starving. I want to try smoothies, thinking maybe something liquid will be easier to grab, go, and sip even though I'm not hungry. How can I make a smoothie that will hold me over? I was thinking about those protein powders at GNC. Are those good to add to a shake, or are those packed with calories and designed for body builders? I was thinking about adding yogurt for protein, but I'm allergic to milk.
