Preheat oven to 350 degrees Fahrenheit. Combine flour with salt and pepper. Dredge each fillet in flour mixture.

In a non-stick skillet melt half the butter over high heat. Fry each fillet for two to three minutes per side. Remove sole from skillet and place in a baking pan. Transfer pan into oven to completely cook the fish for 12 minutes uncovered.

In the same skillet, add the rest of the butter and melt on medium heat. Add lime juice, zest, capers, and garlic to skillet. Stir to mix thoroughly, and bring to a boil for several seconds. Remove from heat and stir in desired amount of chili.

Pour sauce over sole fillets. Serve warm.
