Dice up one onion
Slice your smoked sausage
Shred a portion of your cheddar cheese
Heat some oil in a large skillet
Brown the smoked sausage really well
Remove the sausage, but leave all of those drippings in the pan
Add your diced onion and cook until softened, scraping up all of those brown bits from the bottom
Add about half a box of penne pasta
Add the entire jar of Alfredo sauce
Add 3 cups of water
Add the frozen broccoli
Add the smoked sausage back into the pan
Bring everything to a boil
Cover and simmer for about 10 to 12 minutes, stirring occasionally
Once that pasta is tender, stir in your shredded cheddar cheese
Let everything sit for a few minutes so that sauce can thicken
