Heat oil in a large skillet over medium-high flame. Add the four chicken burgers and cook through, crumbling burgers into taco-style meat as you cook. Set aside and keep warm. In a separate skillet, heat additional oil and lightly sauté tortillas until soft, turning frequently. Or, wrap tortillas in paper towels and place them in the microwave for about 30 seconds. Fill tortillas with crumbled chicken and top with your favorite garnishes.
