Love this salad! Since it is quite rich, pair it with a lighter main dish, such as grilled chicken.
Combine vinegar, oil, sugar, mustard, and pepper in a bowl. Refrigerate dressing until ready to serve.
Place avocados, mangoes, and lemon juice in a bowl. Mix gently until just combined.
Place lettuce in a large bowl or platter. Add avocado-mango mixture, walnuts, bacon, and the dressing. Toss and serve.
