Blend your chipotles in adobo into a paste, either in your blender or with your immersion blender.
Combine strawberries, chipotle paste, sugar, lemon juice and salt in a medium saucepan and cook over medium heat until the strawberries are fully cooked and all the juice has come out, about 5 minutes.
When your strawberries are soft and bubbling, blend your sauce using your immersion blender to get a sauce. It should be about the consistency of barbeque sauce.
Cook for an additional 3-5 minutes to thicken the sauce to the proper consistency.
Separate 1/4 of the sauce into a bowl and set aside.
For The Pork
Heat your BBQ over medium heat.
Season your tenderloins with salt.
Cook on your BBQ over medium heat. Using a bbq brush, glaze your pork with the sauce each time your turn it. You should glaze each side at least twice, cook on each side for a few minutes at a time until cooked through to your liking, I prefer my pork at around medium or an internal temperature of 140°F.
Serve your pork with the reserved sauce and enjoy!
