In a shallow dish, combine the flour, salt, and pepper. Dredge the chicken tenders in the flour mixture, shaking off any excess.
In a skillet over medium-high heat, melt 2 tablespoons of butter. Cook the chicken tenders in two batches, searing both sides until a golden brown crust forms (about 2-3 minutes per side). The chicken is ready when the internal temperature reaches 165°F/74°C. Remove the cooked tenders onto a plate. Melt the remaining butter and cook the remaining chicken tenders.
Deglaze the pan by adding about ¼ cup of water, scraping up any bits stuck to the bottom. Allow the liquid to reduce slightly.
Add the garlic and cook for 30 seconds. Then, stir in the honey, soy sauce or tamari, vinegar, and red pepper flakes (if using). Cook for 1-2 minutes until the sauce is heated through and begins to thicken. Return the chicken to the pan, flipping it to coat with the sauce.
Garnish with chopped fresh parsley and serve over jasmine rice, noodles, or cauliflower rice.
