In a very large skillet or saute pan, cook bacon over a medium heat until brown & crispy, but don't burn it!
Meanwhile, boil the pasta in a large pot and drain. Scoop the bacon out of the pan and let it rest on paper towels, leaving the drippings behind in the pan.
Scoop 1 tablespoon of the drippings and put in the pot with the drained pasta, using it to flavor the pasta and keep it from sticking. Scoop the rest of the drippings into a container to save for later use, but leave about a tablespoon in the pan to saute the onions in.
Once the onions are softened (cooking over a medium heat), add the salt & pepper and garlic. Let it continue cooking until the garlic is soft then add the peas. Stir and let them heat through, then add the pasta and bacon, stirring until combined then top with the parmesan cheese.
Dinner is done & delicious!!!
