Cut 2 large ripe avocados in half, remove the pit, and scoop the flesh into a food processor. Add 3 tablespoons tahini, 3 tablespoons lemon juice, ½ clove garlic (grated), ½ teaspoon salt, and ⅛ teaspoon black pepper.
Blend until smooth, stopping once or twice to scrape down the sides.
Taste and adjust adding more salt or lemon juice before serving. Transfer to a bowl and serve as a dip or spread. We like to drizzle with good olive oil, cilantro, and sprinkle with sesame seeds.
