Broil the Fish
Preheat your broiler. Place the fish on a broiler pan or baking sheet. Lightly spray with olive oil and season generously with your favorite seafood seasoning. Broil until the fish is firm, opaque, and flakes easily—about 6–8 minutes depending on thickness. Let cool slightly, then flake with a fork. Squeeze lime juice over the fish and set aside.
Make the Filling
In a large bowl, combine softened cream cheese, sour cream, ground coriander, and cumin. Mix until smooth. Stir in the chopped green chiles, 1 cup of shredded Monterey Jack cheese, chopped cilantro or parsley, dill (fresh or dried), and season to taste with salt and pepper. Fold in the flaked fish gently to keep some texture.
Assemble the Enchiladas
Lightly spray a casserole or baking dish with olive oil. Spoon 3 to 4 tablespoons of filling along the edge of each tortilla, then roll tightly and place seam-side down in the dish.
Add Cream & Cheese
Pour heavy cream over the enchiladas until just covered. Sprinkle with the remaining Monterey Jack cheese and grated Parmesan.
Bake
Preheat oven to 375°F. Bake for 45 to 50 minutes, or until the top is golden brown and bubbly.
Garnish & Serve
Top with sliced avocado, chopped green onions, and fresh cilantro or parsley. Serve warm.
