1 (6 ounce) package lime flavored Jell-O® mix
1 3/4 cups boiling water
1 (8 ounce) package cream cheese, softened
1/2 cup chopped celery
1 1/2 avocados, peeled and mashed
1/2 cup mayonnaise
1/2 teaspoon salt
1 teaspoon onion juice (optional)
6 butter lettuce leaves, rinsed

1/2 cup mayonnaise
1/4 cup confectioners’ sugar, or to taste
1 tablespoon lemon juice, or to taste
1/2 cup pecan halves, toasted

1. In a medium bowl, dissolve the gelatin in the boiling water. In another bowl, mix together cream cheese, celery, avocado, 1/2 cup mayonnaise, and salt. Mix in onion juice, if using. Gradually stir in the gelatin mixture. Pour into an 11×7 inch glass baking dish, and refrigerate until set.
2. Cut the gelatin salad into squares, and serve each square on top of a leaf of butter lettuce. Make the salad dressing by mixing the 1/2 cup mayonnaise with confectioners’ sugar and lemon juice to taste. Drizzle dressing over squares, and garnish with toasted pecans.
