Prep. Soak the wooden skewers in a bowl of water for about 10 minutes so they don’t burn in the oven. Preheat the oven to 425°F and line a baking sheet with parchment or foil, then set a rack on top. Set aside.
Prepare the salmon. Take the partially thawed fillets and cut them into long pieces; you’ll need 8 in total. I get four fillets - they each weigh about 3 to 4 ounces - and I cut each fillet, longwise, into two pieces.
Thread. Poke the skewers through each piece of salmon in a threading motion. Then wrap a slice of prosciutto around the salmon.
Season. Brush each skewer with olive oil and season lightly with black pepper. Add a pinch of salt only if you want extra, but prosciutto is already salty.
Bake. Arrange the skewers on the rack and bake for 10 to 12 minutes, or until the salmon is cooked through and the prosciutto is crisp around the edges.
Serve. Remove the salmon kabobs from the oven and serve.
