Preheat the grill or a grill pan over high heat.
Combine the honey, saffron, pepper, kosher salt, lemons and 2 to 3 tablespoons water in a small saucepan and stir to combine. Simmer gently over medium heat, stirring occasionally and adding more water or honey as needed, until the consistency thickens and the lemon slices start to break down, about 25 minutes.
Meanwhile, sprinkle the opah on both sides with sea salt and pepper and lightly coat with the olive oil. Make sure the grill surface is clean, and then grill the fish on one side on the hottest part of the grill about 5 minutes, rotating halfway through to create diamond grill marks after about 3 minutes. Flip the fish using a fish spatula and repeat on the opposite side, cooking until fish is medium-rare, almost medium, another 4 to 5 minutes. Squeeze the lemon juice over the fish just before removing it from the grill and transfer to a serving plate. Brush the tops of the fish with a hint of olive oil and then cover with the candied lemons, followed by the basil, dandelion greens, parsley and chives.
