Blanch green beans in a large stock pot of salted boiling water for 2 minutes. Drain and set aside.
Using the skillet from the bacon, melt butter over medium heat. Add shallots, garlic and red pepper flakes and saute for 1 minute. Add beans and Dijon Maple Sauce and continue to saute until beans are evenly coated in the sauce and beans and cooked to desired crisp-tenderness.
Taste and season with additional red pepper flakes, salt and pepper to taste. Put green beans into a large bowl and top with caramelized pecans, bacon, and feta cheese before serving!
