Roast until an instant-read thermometer inserted in the center registers 145 degrees F, 12 to 15 minutes.
Meanwhile, heat 1 tablespoon oil in a large pot over medium-high heat.

Transfer to a bowl; cover to keep warm.
Heat the remaining 1 tablespoon oil in the pot over medium heat.
Add garlic, sage and crushed red pepper; cook for 30 seconds.
Add beans, 1/2 cup broth and the remaining 1/8 teaspoon salt.
Mash with a potato masher until almost smooth.
Reduce heat and cook, stirring often, until hot, about 5 minutes.
Remove from heat and cover.
Transfer the pork to a clean cutting board and let rest for 5 minutes.
Bring to a boil over medium-high heat, scraping up any browned bits.
