1 ripe avocado
1/2 cup diced onion
1 tbsp minced garlic
1 diced tomato
2 Tbsp lime juice
salt and pepper to taste

Cut the avocado in half, remove the seed and skin and roughly chop.  Place in a medium mixing bowl.  Mash with a fork.  Add the rest of the ingredients and mix well.  Refrigerate at least an hour to let the flavors mingle!   Serve with tortilla chips or for an even lower fat option, whole wheat pita triangles!
