Ingredients
1/2 ripe avocado
1 small clove garlic
1/4 cup dill sprigs
2 tablespoons fresh lemon juice
3/4 cup buttermilk
Kosher salt and freshly ground pepper
1 large head butter lettuce, leaves separated and torn into 2-inch pieces
1 small Persian cucumber, thinly sliced
8 slices bacon, cooked and crumbled
2 radishes, thinly sliced
Preparation
Combine avocado, garlic, dill, lemon juice, buttermilk, and 2 tablespoons water in a blender; puree until smooth. Season with salt and pepper. (If dressing is too thick, add more water, a tablespoon at a time.)
Toss together lettuce, cucumber, bacon, and radishes in a large bowl; season with salt and pepper. Drizzle with 1/4 cup dressing. Serve remaining dressing on the side, or refrigerate in an airtight container up to 2 days.
