Melt the butter over medium heat in a large skillet.
Sprinkle the chicken with salt and pepper. Then place the chicken in the skillet.
Pour lemon juice, white wine, and sage over. You want the white wine to almost submerge the chicken, add more wine if you need to.
Once you see that the chicken is almost cooked through, flip it over. The first side will take about 4 minutes to cook. Once flipped, the second slide will cook in about 3-4 minutes.
Serve the chicken with the lemon, white wine, sage sauce in the pan spooned over.
If you would like, you can also garnish with some fried sage leaves.
