Mix together the honey, chipotle peppers and adobo sauce, 1 tablespoon of the olive oil and juice and zest of 1 lime in a small bowl to make a glaze. Set aside.
Put the broccoli slaw in the bottom of a baking dish. Drizzle with the remaining olive oil and season with a pinch of salt and pepper, then toss. Scatter over the sliced sweet peppers and chiles. Top the slaw and peppers with the cod fillets. Season the cod with a good pinch of salt and pepper. Pour the chipotle glaze over the fish and around the baking dish over the slaw.
Roast until the fish is cooked through and flaky, 18 to 20 minutes. Remove from the oven and immediately squeeze over the juice of the other lime. Flake the cod into large chunks and sprinkle over the chopped cilantro.
To build the tacos, place a couple chunks of cod into each taco shell. Top with a pinch of slaw, some sliced avocado, sour cream and hot sauce. Garnish with a lime wedge and squeeze over a little juice before eating.
