Recently I savored a delicious vegetable dish at a buffet dinner at a Turkish restaurant in Anaheim, California. It was a simple dish of sauteed eggplant cubes and green pepper strips stewed in tomato sauce with a healthy dose of hot pepper flakes. The dish was delightful topped with jajik, also known as cacik, a sauce of yogurt, grated cucumber, garlic and dill. The tangy, creamy yogurt was a wonderful match for the sweet and spicy tomato sauce. I have enjoyed this association of tomato-sauced vegetables with yogurt from time to time, in diverse cuisines. Yogurt often accompanies givetch, a Balkan tomato-sauced vegetable stew. The pairing is also common in Afghan cuisine. At Khybar, an Afghan restaurant in Los Angeles, fried eggplant cooked with tomatoes, sweet peppers and garlic is topped with yogurt and served with aromatic basmati rice. The chef also sauces ashak, leek-filled tortelloni-type dumplings, with a savory tomato sauce and dollops of rich yogurt. The first time I remember tasting cooked vegetables matched with tomato sauce and yogurt was at a French cooking school in Paris. At Ecole de Cuisine La Varenne we learned to make an impressive eggplant charlotte of fried eggplant slices that lined a mold filled with layers of eggplant, tomato sauce and yogurt, that was baked and turned out of its mold like a cake. Vladimir Mirodan, author of The Balkan Cookbook, pairs sour cream instead of yogurt with tomato sauces, cooking stuffed peppers, stuffed zucchini or stuffed onions in tomato sauce and either finishing the sauce with sour cream or spooning a dollop of sour cream on top. For Succot, since "Mediterranean-cuisine vegetables" like eggplant, zucchini and peppers, as well as tomatoes, are at the height of their season, it's a good idea to feature them on holiday menus. Whether you saute one vegetable or stew several together, you'll find that partnering them with tomato sauce and yogurt makes an easy, refreshing, flavorful holiday dish. ROMANIAN VEGETABLE CASSEROLE Vegetable casseroles like this, both meatless and with meat, are popular throughout the Balkans. An assortment of vegetables is layered with sauteed onions, peppers and tomatoes and baked with garlic and herbs until tender. I like this casserole as a vegetarian main course accompanied by rice or pasta. Top it with Yogurt Cucumber Dill Sauce (see next recipe). â€¢ 4 Tbsp. extra virgin olive oil or vegetable oil â€¢ 3 medium onions, halved, sliced thin â€¢ 2 sweet red peppers, cut in strips (about 1 cm.) â€¢ salt and freshly ground pepper â€¢ 700 gr. ripe tomatoes, chopped, or two 400-gr. cans tomatoes, drained & diced â€¢ 4 medium-sized boiling potatoes, cut in 2-cm. cubes (450 gr.) â€¢ 2 celery stalks, diced â€¢ 110 gr. mushrooms, sliced â€¢ 110 gr. green beans, ends removed, halved â€¢ 2 carrots, cut in small dice â€¢ 1 small eggplant (about 450 gr.), cut in 2-cm. cubes â€¢ 2 medium zucchini or pale-green squash (kishuim), cut in 2-cm. cubes â€¢ 3 Tbsp. tomato paste â€¢ about 3â„4 cup vegetable broth â€¢ 4 large garlic cloves, minced â€¢ 1â„4 tsp. sugar â€¢ 1 tsp. dried thyme â€¢ 1â„4 cup chopped parsley Preheat oven to 175Âº.

YOGURT CUCUMBER DILL SAUCE This creamy sauce is good with vegetable casseroles or with simple vegetable sautes or stews. Use any kind of yogurt you like. The sauce is especially good made with sheep's milk yogurt. â€¢ 2 small cucumbers â€¢ 2 cups plain yogurt â€¢ 2 to 3 Tbsp. chopped fresh dill or 2 tsp. dried â€¢ 1 garlic clove or 1 green onion, finely chopped â€¢ salt and freshly ground pepper â€¢ cayenne pepper to taste Peel cucumber and coarsely grate it.

EGGPLANT WITH TOMATOES AND YOGURT This savory dish is inspired by the elaborate eggplant charlotte I learned to prepare in Paris. This recipe uses the same elements to make an easy-to-prepare dish. Serve it as a meatless Succot dish, accompanied by rice pilaf.
