For the house style couscous, heat olive oil in a large non-stick skillet. Heat mustard seeds in it until they “pop”.
Add cashews and allow to “toast” until light brown. Add diced vegetables and curry powder and sauté briefly.
Deglaze with hot water and add raisins. Add salt and pepper and simmer until vegetables are cooked (about 10 minutes).
Add the couscous and let it swell for a few minutes. Add a little more hot water if necessary. Cut cocktail tomatoes into quarters and stir in.
Season to taste, sprinkle with chopped parsley and serve the couscous in the style of the house.
