In a medium size saucepan, heat butter. Add the onions, celery, and bell peppers and saute approximately 3-5 minutes or until vegetables are soft.
Stir in the whipping cream and bring to a boil.
Reduce heat to medium and stir in seasoning, lemon juice, and 1/2 cup Parmesan cheese. Cook an additional minute.
Add shrimp and cook over medium heat until shrimp are no longer pink, approximately 5 minutes. Turn off stove. Let mixture cool slightly so it thickens.
Divide the mixture into 2 or 4 ovenproof dishes.
In a small bowl, combine the crust ingredients: seasoning, almond flour, and grated Parmesan cheese. Sprinkle mixture evenly over the top of each dish. Spray tops lightly with cooking spray.
Place ovenproof dishes in the oven and bake 10 minutes or until edges bubble and the top starts to brown.
Garnish with fresh parsley.
