In a small bowl combine salt, pepper, garlic, and sage to make a paste.
Rub this mixture all over the tenderloin.
In a very large skillet, heat ¼ cup olive oil to medium high heat and place the tenderlion in the skillet. (If my tenderlion is too long, I will cut it in half.)
Brown each side for 2 minutes. (I do four sides, rolling the tenderloin)
Spray the bottom and sides of the slow cooker with vegetable spray and place tenderloin inside.
Cook tenderloin on high for four hours.
In a small saucepan, combine brown sugar, cornstarch, balsamic vinegar, water and soy sauce. Heat over medium heat for about 4 minutes until sauce thickens.
When the tenderloin is cooked, remove from heat and place on a serving platter.
Slice tenderloin in your desired thickness.
Spoon the glaze over the top. I place the remaining glaze on the table in a serving dish for those who would like extra. (Believe me it is so good, you will want to drown your pork in it.)
