Preheat the grill. Aim for medium heat, about 375–400°F. If using charcoal, let coals settle to a steady medium.
Prep the jalapenos. Slice each pepper lengthwise and scoop out seeds and membranes with a small spoon.
For less heat, remove more of the white ribs.
Make the filling. In a bowl, mix cream cheese, cheddar, green onions, garlic, salt, pepper, smoked paprika, and lime juice until smooth.
Fill the halves. Spoon the mixture into each jalapeno, slightly mounding the top. Don’t overfill or it may spill on the grill.
Optional bacon wrap. Wrap each filled pepper with a half slice of bacon and secure with a toothpick. If skipping bacon, brush the pepper skins lightly with olive oil.
For crunch, sprinkle a little panko on top.
Grill over indirect heat. Place peppers cut side up on the cooler side of the grill. Close the lid and cook 10–15 minutes, until peppers are tender and cheese is bubbling. If using bacon, add 5 more minutes.
Finish with a quick sear. Move peppers to direct heat for 1–2 minutes to crisp bacon or get light char.
Watch closely to avoid flare-ups.
Rest and serve. Let cool 3–5 minutes. Finish with a drizzle of hot honey or barbecue sauce if you like. Serve warm.
