In a large, high-sided skillet or medium heavy-bottomed pot over medium heat, heat oil. Add bacon and onion and cook until onion is translucent and bacon is beginning to crisp, 6 minutes.
Add cumin and smoked paprika and cook until fragrant, 1 minute. Add beans and chicken broth or water and stir to combine, scraping any burnt pits from the bottom of your skillet. Stir oregano into the beans.
Bring mixture up to a low simmer and cook, stirring occasionally, for 15 minutes, adding more broth or water ¼ cup at a time if pan is looking dry.
Before serving, remove oregano stems and season to taste with salt.
