Place all of the crust ingredients in a food processor and process until mixture is fine crumbs.
Place lightly beaten egg in a shallow dish.
Preheat skillet over medium high heat, and melt the 2 Tablespoons of butter.
Dip Tilapia filets in beaten egg mixture, then press one side of the fish into the pecan crumb mix. (You may need to press some on with your fingers.)
Immediately place fish, crumb side down, into the hot skillet.
Cook, uncovered, about 5-6 minutes, or until a crisp crust has formed.
Carefully flip fish over and cover pan with a lid.
Cook for 3-4 more minutes, or until fish flakes easily with a fork.
Sprinkle with salt, to taste. Top with Lime Dill Yogurt Sauce and enjoy!
