How to Make It
Cook bacon in a large skillet over medium-high 5 minutes or until crisp. Remove with a slotted spoon. Sprinkle fish with 1/4 teaspoon salt and 1/4 teaspoon pepper. Add fish to drippings in pan; cook 4 minutes on one side or until golden. Remove fish from pan (fish will not be cooked through).
Add sliced fennel and bell peppers to pan; sauté 5 minutes. Reduce heat to medium-low. Add kale to pan; arrange fish on top of kale. Add stock to pan; cover and cook 6 to 8 minutes or until kale is wilted and fish flakes easily when tested with a fork. Sprinkle with bacon, remaining 1/4 teaspoon salt, remaining 1/4 teaspoon pepper, parsley, fennel fronds, and vinegar.
