Chop and prep your veggies.
In a large pot or skillet, add the oil and onions. Cook the onions until they're starting to become translucent.
Add the bacon and cook until mostly done, around 10-15 minutes.
Add the carrots, celery, and mushrooms, and cook further until soft, about 15 more minutes.
Add the lamb and cook until it's browned, about 10 minutes.
Add the salt, pepper, garlic powder, and paprika, and mix well.
Add in the chicken broth, stir, and boil to cook about half of it off, another 5-10 minutes.
