What you do:
Heat oven to 350. Combine the honey, chipotles, adobo, cilantro and garlic and set aside. Meanwhile, heat the oil in a large skillet over medium heat. Trim fat from tenderloins and season with salt, pepper, cumin and chili powder. Sear in olive oil browning all the sides. Transfer to a lightly oiled baking pan (or leave in skillet if it's oven proof.) Roast for about 15 minutes and brush with the chipotle mixture. Continue roasting fro another 15 minutes. Let rest for 5 minutes before slicing and serving.
