Two 14 oz. cans artichoke hearts, drained
8 oz. cream cheese (can use low or non-fat)
1 cup real mayonnaise (can also use low or non-fat here)
1 cup grated Parmesan cheese
1 cup frozen spinach, thawed
dash of salt
freshly ground black pepper
Chop artichoke hearts in food processor, i usually chop one can very fine & leave the other pretty chunky.
Then mix together with cream cheese, mayo, cheese, spinach & spices. Use your discretion on the cayenne pepper, i usually add about half a palm-full, it still has some kick, but isn't unbearable.
Transfer to slow cooker & cook on LOW for 1-2 hours, or just put on "keep warm" *(if you have that setting) prior to serving.
