Our go to summer appetizer is homemade guacamole served with a big bowl of tortilla chips. My only advice is make the guacamole just before serving as it will otherwise turn brown.
Ingredients: 2 avocados, 1 garlic clove minced, 1 ripe tomato chopped, 1 lime juiced, salt and pepper to taste, and 1/2 cup of diced red onion.
