I have been using this spinach dip since 1981, it has an equal mix of mayo & sour cream, giving it a more neutral taste, which lets the soup & spinach play a larger role in the taste. It's very easy, and the recipe is requested whenever I make it.

Make at least one day in advance. This recipe makes
1 quart

Fabulous Vegetable (Spinach) Dip

1-10 oz box frozen chopped spinach, defrosted
& squeezed dry
1-8 oz can water chestnuts, drained & chopped
1-1 5/8 pkg dried vegetable soup mix (I use Knorr's-
I think it is the best one out for this, but feel free
to substitute)
2 Cups sour cream
2 C mayonnaise

Combine all ingredients. Refrigerate. Serve w/tortilla chips & carrot sticks.
