2 cups frozen precooked white rice (unthawed)
1 cup canned coconut milk (regular or light)
Juice of 1 lime
½ tsp. crushed red pepper flakes
1 cup frozen shelled edamame (unthawed)
Kosher salt and freshly ground black pepper
4 skinless fillets halibut (each 1 inch thick; about 2 pounds total)
4 tsp. chopped fresh cilantro leaves
2 limes, sliced into thin rounds

Preheat the oven to 400°F with a rack in the center position. Stir together the rice, coconut milk, lime juice, red pepper flakes, edamame, and a pinch of salt in a medium-size bowl. Set aside. Cut four sheets of parchment paper, each 18 inches long and 15 inches wide. Fold each piece of parchment in half (short side to short side). Use scissors to cut each folded piece so that when you open the parchment it looks like a big, fat heart (sort of like you’re making a parchment Valentine). Spoon the rice mixture onto one side of each heart, just next to the crease. Lay a halibut fillet on top of each rice pile and sprinkle each fillet with salt, pepper, and 1 tsp. of chopped cilantro. Arrange 3 or 4 overlapping lime slices atop each fillet. Seal the parchment packages: Fold the empty half of each heart over the filling and crimp the edges in overlapping folds as you go, until each package is completely closed up and airtight. Carefully place the closed packets on two sheet pans (two packets per pan), and bake until the fish is opaque, about 20 minutes (feel free to unfold the edge to peek inside one of the packets toward the end to check the fish). Carefully open the packets (watch out for the steam) and slide the rice and fish into bowls, or transfer the packets to plates so each guest can open his or her own at the table. Serve immediately, while the rice and fish are still warm.
