In a cast iron skillet, cook bacon to your desired level of doneness. Remove from skillet and place on a plate with a paper towel to drain. Set aside.
In the same skillet, cook pork sausages until completely cooked through. Add the baked beans to the skillet and let simmer until the mixture is slightly thicker and darker, about 5 minutes.
Add the eggs on top of the beans and cook through, about 5 minutes.
Add bacon back to skillet then serve with tomatoes and toast.
