To create a variety of taste from the same basic recipes, substitute olive oil with rapeseed, safflower, grapeseed, corn, almond, walnut or flaxseed oil. Adding spices like cumin, Cajun or paprika to yogurt dressing creates different flavors. Use other citrus juice and honey for a sweeter dressing without adding extra sugar. Herbs like rosemary, tarragon, thyme and roasted nuts and seeds used sparingly will enhance the flavor, fragrance and texture to the basic dressings. Get creative and enjoy your salad!
