2 ripe avocados
3 tablespoons diced red onion
1 jalapeño pepper, stems and seeds removed, finely diced (optional)
3 tablespoons cilantro leaves
Juice from half a lime
1/2 teaspoon salt
1/2 cup ripe tomatoes, seeded and diced (optional)
Using a fork or potato masher, mash the avocados. Add remaining ingredients. Add more salt if needed. Serve right away with tortilla chips.
Notes: You really can't make this ahead of time. Make it and eat it right away!
