Ingredients for baked tilapia:

• 5 tilapia fillets (1lb)
• 8 oz bag of fresh spinach
• 3 tbsp butter, sliced
• 1 cup shredded Monterey jack cheese

Ingredients to make sauce for baked tilapia:

• 1/2 cup mayonnaise
• 1/2 cups grated parmesan cheese
• 2 cloves garlic, crushed
• 1/2 cup sour cream
• 1 tsp old bay seasoning
• 1/2 tsp adobo seasoning
• 1/4 tsp black pepper
• 1/4 tsp salt

NOTE: Use as much spinach as you can pack into your baking dish because spinach does shrink quite a bit.

1. First, pack spinach onto the bottom of a baking dish. Top with butter slices and layer the fish fillets over the top

.

2. Then, combine the sauce ingredients and evenly spread over the top of the casserole. Finally, sprinkle with cheese and bake in a preheated to 500 degrees F oven for 10 minutes.

Note: The thicker the fish fillets the longer you may need to bake your fish.
