Preheat the oven to 350°F (175°C). Pat the fish dry, inside and out. Salt generously inside and on both sides outside, then place on a lightly oiled piece of foil that is large enough to enclose the fish. Stuff the fish cavity with cumin, coriander, chopped parsley, lemon slices, garlic. Optionally add vegetables. Fold the foil over the fish lengthwise, tightly closing the top seam to trap the steam.
Place the foiled fish on top of the hot sheet pan and bake about 30 minutes until fork-tender. Remove from heat and add the lemon juice. Serve immediately. Enjoy your meal!!!
