Put the chopped or halved tomatoes and the diced sheep`s cheese in a baking dish, pour over sugar, olive oil and vinegar, season with salt, pepper, basil etc. as you like (garlic is sure to taste very good too). Put the whole thing in the oven at 180 ° for about 20 minutes. Wash the lettuce and distribute it on plates. Then pour the sheep`s cheese and tomatoes over the salad
