Place the salmon fillets in a shallow bowl. Toss well with lemon juice, salt and pepper. Let rest for 15 minutes. Combine the sour cream, minced garlic, dill and lemon juice in a bowl. Cover and store in the fridge until ready to serve.
Add the olive oil in a non-stick skillet over medium-high heat, sear the salmon on both sides, about 3-5 minutes for each side. Serve with the prepared sauce and some mixed salad.
