When I don't have time to prepare anything extensive for lunch, I make a salad, or like today, I chopped up mushrooms and asparagas and stir fry them. When they're nearly finished, I add some mustard or low-sodium MSG-free soy sauce.
The day before yesterday I made "fried rice": I shredded a cup of cauliflower ("rice"), cut up a cup total of mushrooms, zucchini, and scallions, stir fried with a little EVOO and soy sauce, and I LOVED it. Add chicken, and you've got yourself some tasty chicken fried rice for dinner.
Chop up 2 cups of rhubarb (a little more than 2 stalks, usually) into small pieces, boil with a little water until soft, add 2 packets of stevia and a tbsp or 2 of WF strawberry syrup, stir, and you got yourself some tasty "strawberry pie filling."
