Never tried this but looks good and safe. (a huge cheap meal... feed 6 with 1/2 left over (maybe you could half it)
step one: chop an assortment of veggies in large pieces (1 - 2" or larger): small bag of baby carrots, 3 small zucchini, a medium cabbage cut into 8 wedges, medium turnip, 6 small tomatoes cut in half. Toss the whole works into a large roaster. Add 2 cups of chicken broth. Drizzle with olive oil, salt and pepper to taste. Cover and put in a 450 degree oven. Take it out and stir it around every so often. This many veggies takes about an hour to roast.
you can use all sort of other veggies (squash, eggplant, green beans.. it's all good), add some chickpeas if you want.
step two: grill 5 seasoned chicken breasts. Time the grilling so that it'll be done about the time the veggies are done.
step three: prepare 2 packages of couscous. this part takes 5-10 minutes, so start just about when you think everything is done.
putting it all together: get the biggest platter you can find and pile on the couscous. make the edges somewhat higher than the centre so that you have created a kind of bowl for the veggies.
spoon on all of the veggies that you can fit; mound them. pour over any stock that has accumulated in the roaster.
cut the meat into bite sized pieces and arrange them all over the veggies, and around the couscous if you have any room.
