Mandarin Orange Salad

My mom recently dug this recipe out of her collection to make for Easter dinner.  It was delicious!  So, I have to share.  The dressing is sweet and tart and very easy to make.  Hope you like it!

For the Salad:

4-5 cups mixed lettuce, chopped (I used a mix of fresh spinach, romaine, and red leaf lettuce)
1/2 cup toasted and chopped pecans
1 small can mandarin oranges, drained
1 can pineapple chunks, drained

For the Dressing:

1/2 cup sugar
1 tsp dry mustard
1 tsp celery seed
1/4 tsp salt
1/3 cup honey
1/3 cup red wine vinegar
1 tbsp fresh lemon juice
1 tsp minced sweet onion
1 cup extra virgin olive oil

Place all the dressing ingredients in a blender, except for the oil.  Blend.  Slow stream in the oil and continue to blend until well incorporated.  Place the lettuce, oranges, pineapple, and pecans in a salad bowl.  Pour the dressing over and toss.
