10 oz box frozen spinach, thawed
1/2 c fat-free sour cream
1/2 c fat-free cream cheese, softened
2 Tbs chopped red onion (more to taste)
3 canned chili peppers, chopped finely (optional)
Thaw spinach and squeeze out water very thoroughly, it works well to press between some paper towels to really get the water out. Mix with remaining ingredients in a food processor or blender. With my older, less powerful blender it works best to do the sour cream, cream cheese first, then add peppers and onions, then add in the spinach a little at a time.
