One of the great pleasures of dining in France's lovely Provence is that a great deal of the eating is done outdoors. I fondly remember atmospheric luncheons in home gardens and dinners at seaside tables, but especially recall picnics just about anywhere - at the beach, along the roadside, on a hillside or in an olive grove.

The people of Provence have long been blessedwith a rich repertoire of natural food products: The finest of olives and olive oil, grapes and wine, flavorful vegetables, aromatic herbs, tender sweet fruits and bountiful sea-food.

The cuisine reflects Greek-Roman her-itages with some Italian influence in the East and Spanish in the West. But Provencal cooks have remained partial to dishes made with local foods.

Much of the Provencal fare is excellent for picnics as it will withstand the heat and travel well. One picnic, or several, could feature an assortment of coldhors d'oeuvre such as pickled mushrooms, marinatedartichoke hearts, rice-filled tomatoes and green peppers, crisp raw vegetables, garlic sausage or salami, herb or anchovy garnished hard-cooked eggs, dried white bean or green bean salads vinaigrette, salads made with chic-peas, lentils or rice and vegetables, and cooked meats, with grapes, peaches, apricots, figs, cheeses, French bread and wine.

Such well-known Provencal dishes as ratatouille, salade Nicoise and aioli (garlic mayonnaise) with raw vegetables are also good picnic fare. I also favor crisp raw radishes with green leaves intact on slices of buttered cursty bread.

Given below are recipes for dishes that can be prepared in the home and taken on picnics to be enjoyed with or without foods and dishes mentioned above. COLD TOMATO OMELETTE (1 or 2 servings)
