In a saucepan, combine 2 TBLS butter, flour, and onion. Cook over medium heat until onions are tender, about 5 minutes.

Add cayenne pepper and salt, and simmer for 10 minutes.
Add cream, and simmer 5 minutes more.  Remove from heat and set aside.
Season shrimp with blackening seasoning.
Melt 1 TBLS butter in a hot saute pan. Saute shrimp in butter about 2 minutes per side.
Add spinach, mushrooms, crab meat and green onions. Saute until mushrooms and spinach soften, about 2 minutes.
Fold into cream sauce and bring to a simmer.
Add half of the grated mozzarella.  Simmer another couple of minutes so the cheese melts.
Slowly add xanthun gum as needed to thicken.  (A little goes a long way.  Don't overuse.)
Pour mixture into a heatproof dish (or two). Top with remaining grated cheese.
Place under a broiler until cheese melts, about 3 to 4 minutes.
Top with chives if desired and serve immediately with garlic bread OR pork skins for keto.
