Mix mustard, maple syrup, garlic, shallot, rosemary and thyme. Spread evenly over entire surface of tenderloin.

Transfer to a sauté pan and add roasted red peppers, jalapeño, cilantro, lime zest and orange zest. Stir to mix.
Allow sauce to stand for at least 30 minutes for flavors to blend. Warm sauce over low heat before serving. Do not boil. Add salt to taste.
