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.
