Recipe I found on Moroccan Food on About.com. It states that you can add a variety of vegetables (your choice), so would I add carrots, celery along with the suggested bell pepper as my choices. Here is what is stated about the recipe: "This antipasto-style pasta salad gets a Moroccan twist with ingredients common in Morocco – cured meat, olives, Edam cheese, and veggies – and an easy cooked vinaigrette that takes just minutes to prepare. Use my suggestions below, or personalize the salad with up to 3 1/2 cups of your own additions such as marinated artichokes, pimientos, black olives, mushrooms, cooked baby carrots or cauliflower or broccoli florets. Allow chilling time before serving. The tri-colored pasta salad is intended as a side dish, but you may find yourself eating enough of it to make it your main course!"
