Sauces for your 2 cups of vege stirfry

Maggi - Stirfry Creations Honey, Soy and Garlic Chicken .. am I allowed to use this on optifast plan? am in intensive phase so think not. Find it so hard to find something yummy and easy to cook the veges in, I'm not the best cook. Anyone know of any good supermarket sauces that are allowed?
