Chopped Salad with Creamy Mustard Vinaigrette

My daughter Jennifer made this chopped salad for a family dinner.  If I remember correctly she had this salad at a restaurant and had to duplicate it at home.  Jennifer gave me her recipe on two yellow post-its which I still have.  There is something special about a recipe that is handwritten. Our family loves blue cheese, so this was an absolute winner.

Ingredients:

1 head of Romaine or Iceberg lettuce chopped

3/4 cups tomato diced

1 jar  artichoke hearts chopped, not marinated

1 large ripe avocado diced

3/4 cup crumbled bacon

6 oz blue cheese

1 can (1 cup)heart of palm diced 

1/4 cups minced red onion

Creamy Mustard Vinaigrette:

1/4 cup champagne vinegar or rice vinegar

1/2 cup olive oil

1 Tablespoon Dijon Mustard

1 teaspoon minced garlic

1 Tablespoon mayonnaise

1/2 teaspoon salt

1/4 teaspoon pepper

Whisk ingredient together until emulsified.
