Preheat the oven to 425°F (220°C). Set a wire rack on a rimmed baking sheet and lightly coat the rack with cooking spray.
Set up three shallow bowls: the first with flour and salt mixed together, the second with eggs and coconut milk whisked together, and the third with shredded coconut, panko, salt, garlic powder, and black pepper combined.
Pat the chicken tenders dry with paper towels.
Working one at a time, dredge each tender in the flour and shake off the excess, dip it in the egg mixture and let the excess drip off, then press it firmly into the coconut-panko mixture, turning to coat all sides and pressing gently so the coating adheres.
Place the coated tenders on the prepared wire rack in a single layer with space between each piece.
Lightly spray the tops of the coated tenders with cooking spray, or brush with a small amount of melted coconut oil.
Bake for 18 to 22 minutes, until the coconut coating is deeply golden brown and the chicken is cooked through to an internal temperature of 165°F (74°C).
Stir together the sweet chili sauce and lime juice in a small bowl to make the dipping sauce.
Serve the chicken strips immediately alongside the dipping sauce.
