Avocado Salad

(based on Salad Time, Judaica Press 2007)

1 Bag romaine lettuce (we use spinach)
1 red onion, diced (we use 1/2)
2 avocados, cubed
2 cans of mandarine oranges
strawberries (we add this, not part of original recipe)
handful of slivered almonds

Dressing:
1/2 c oil (we use 1/4 cup, add 1/4 cup water instead)
1/3 c vinegar
1/2 c sugar (splenda; can use a little less)
2 tsp dried mustard
2 tsp salt
handful of poppyseeds (we don't use, because we don't have them)
