1 c. sour cream
1 c. mayonnaise
1/2 c. bacon bits
1/2 c. water chestnuts, chopped
1 onion, chopped
2 (4 oz.) pkgs. Ranch buttermilk dressing mix
2 pkgs. frozen chopped spinach, cooked (I used two 10 ounce package, which was too much. Next time I'd try 1 1/2 packages.)
1 (8 count pkg.) flour tortilla shells (dinner size - about 6)

Mix together - except shell; spread 1/4 inch thick and roll. Store covered overnight, slice the next day.
