  Spices bring to life even the blandest of dishes. Loved by carnivores and vegetarians alike, spices can define a tasty dish. For a vegetable based entree, using spices such as basil and oregano makes any item into an Italian feast. Add some cilantro and chipotle powder for a Mexican fiesta. Fresh lemon pepper adds a gentle spice and sweetness to the dish. Use fresh chopped herbs to change the flavor of soups, pastas and rice dishes. Saute, barbecue, marinate, and bake with these spices and the meal won't miss the meat.
  
  

Oils and Nuts

  Healthy oils are a necessary fat for a vegetarian diet while also supplying a tasty alternative flavoring. Olive oil is a great way to add flavor without bad fats. Saute mushrooms, onions, and other vegetables in a light glaze of olive oil to bring out the richness of their flavors. Baste corn on the cob in olive oil and garlic powder before grilling. Macadamia, peanut, coconut and almond oils all add a distinct flavor to the dish without weighing down the meal.
  
  

Sauces

  The right sauce can transform the same meal with a simple switch in flavor. Vegetarian cooking relies heavily on sauces to add to the range of dishes available. Soy sauce and rice vinegar in a stir-fried vegetable dish gives texture and depth. The same meal prepared with boiled rice and veggies becomes a favorite when adding a white wine lemon sauce. Hot sauce cooked in with mushrooms gives a meaty texture some flare. A garlic marinara over fresh eggplant and noodles makes for a nutrient dense meal with plenty of flavor.
  
  

Variety

  Use new vegetable, fruit and herb combinations to keep the meals from getting bland. Ginger root is a powerful flavor that completely changes the taste of any meal. Fresh lemon or orange juice squeezed into the dish changes the consistency and flavor of vegetables and other fruits. Mix fresh asparagus with a creamy mushroom sauce and paprika. Bold bell peppers and pineapple make a good accent for many dishes, especially items cooked on a grill. Fresh, natural ingredients thrive when combined in vegetarian dishes.
