Skillet Lemon-Garlic Salmon

Heat oil and butter in a large skillet over medium-high heat. Sprinkle both sides of salmon pieces with salt and pepper. Add to the pan and cook, turning once, until both sides are browned and the fish is just cooked through, 5 to 7 minutes. Remove to a plate. Reduce heat to medium and add garlic, lemon zest and lemon juice; cook, stirring, until the flavors have blended, about 30 seconds. Drizzle the sauce over the salmon. Serve with lemon wedges, if desired.
