In a 2 quart saucepan over high heat, heat the broth to boiling. Remove it from the heat and stir in the couscous. Cover and let it stand (off the heat) for 5 (or up to 10 minutes) to allow the couscous to absorb the broth. Fluff it with a fork
Meanwhile, heat the oil in a 10 inch skillet over medium heat. Once the oil is hot, cook the mushrooms, onions, peppers, ginger and garlic until the vegetables are tender-crisp. Stir the mixture often while it is cooking.
When the vegetables are cooked, stir in the soy sauce and lemon juice. Pour it over the cooked couscous, mix it all together and heat it through.
Notes
Toasted Couscous
You can add even more flavor to the couscous by "toasting" it before you add the boiling water. Melt 1 teaspoon or oil or butter in a saucepan, add the couscous and saute it for a few minutes until it becomes fragrant and the grains are slightly colored. Boil the broth in a separate pan, then add the toasted couscous to it and proceed as in the recipe above.This is a healthy side dish recipe, but it makes a great vegetarian main course too.The flavorings are simple in this recipe - just soy sauce and lemon juice. If you like things a bit hot, feel free to add a few chopped Thai chilies to the vegetable mixture. I personally prefer it without, but we all have different tastes.
