While the pasta is coming to a boil, prep all the ingredients.
In a medium fry pan or large saucepan, add the chopped bacon. Cook on medium heat until lightly browned, about 4 minutes.
Add the sliced yellow pepper and cook for 4 minutes.
Add the sliced onion and continue cooking until the onion softens and starts to turn translucent, about 5 minutes.
Add the jarred sauce, and stir to combine with other ingredients.
Add the capers and stir to combine.
When the pasta is done cooking, remove ½ cup of the pasta water before draining. If the sauce looks too thick, add a little of the pasta water until reaching the desired consistency.
Taste and adjust the seasoning with salt and pepper.
