Tunisian mashed-zucchini salad. In this Tunisian salad (pronounced aj-LUKE coo-rah-AH), served as an appetizer with bread, the rich flavoring lifts the blandness of zucchini. Harissa, a spicy North African sauce made with chile peppers and garlic, is available in specialty markets. You can use a good pinch of ground chile pepper instead. (Begin with a small dash--you can always add more.)
