• 3 Haas avocados, halved, seeded and peeled
• 1 lime, juiced
• 1/2 teaspoon kosher salt
• 1/2 teaspoon ground cumin
• 1/2 teaspoon cayenne
• 1/2 medium onion, diced
• 2 Roma tomatoes, seeded and diced
• 1 tablespoon chopped cilantro
• 1 clove garlic, minced

In a large bowl place the scooped avocado pulp and lime juice, toss to coat. Drain, and reserve the lime juice, after all of the avocados have been coated.

Using a potato masher add the salt, cumin, and cayenne and mash. Then, fold in the onions, tomatoes, cilantro, and garlic.

Add 1 tablespoon of the reserved lime juice. Let sit at room temperature for 1 hour and then serve.
