Heat a large pot over medium-high heat with 2 turns of the pan of oil. Add bacon and stir until crisp. Remove bacon to a plate and drain excess fat from pot.
Add beef to the pot and cook over medium-high heat, breaking it up with a wooden spoon. Season the beef with salt, pepper, chili powder, coriander, cumin, oregano and paprika. Add sausage to the pot as the beef browns. Add peppers, celery, onions and garlic. Partially cover pot and cook to soften veggies for about 7-8 minutes.
Add Worcestershire, beer, stock, tomatoes, sugar or honey, and reserved bacon. Bring to a bubble, then reduce heat and simmer chili over medium-low heat for 1 hour, stirring occasionally.
Once finished, serve on slider-size rolls topped with onions and pickled jalapeños, cheese optional.
