Garnish this creamy Mexican-inspired dish with fresh avocados, lime and cilantro for a fiesta in your mouth.
Preheat a broiler.
Arrange the fish on a broiler pan or baking sheet. Spray the fish with olive oil and sprinkle liberally with seafood seasoning. Broil until firm and opaque. Cool the fish and flake with a fork. Dress with the juice of the lime.
In a large mixing bowl, stir to combine the softened cream cheese, sour cream, coriander and cumin. Add the chiles and 1 cup of the Jack cheese, the cilantro or parsley, fresh or dried dill, salt and pepper to taste and the halibut flakes.
Spray a casserole or baking dish with olive oil. Arrange 3 to 4 spoonfuls of the filling on the edge of each tortilla and roll the enchiladas. Set into the casserole seam-side down. Pour the heavy cream over the top of the casserole, just enough to cover, and cover with the remaining Jack cheese and the grated Parm. Chill, covered, for a make-ahead meal. Bring to room temp before baking.
Preheat the oven to 375ºF and bake the casserole brown and bubbly, 45 to 50 minutes. Top with avocado, onions and parsley or cilantro.
