Shrimb and bacon pasta

I made this last night and loved it, but I didn't use a recipe, so I'm putting down what I did so I won't forget. 

Ingredients
1/2-1 lb shrimp
1/2 large onion
2-4 pieces cooked bacon
2-4 cloves of garlic, minced
some shredded parmesan
salt and pepper to taste
olive oil
butter (I used 1.5 TBSP altogether, but could use more :))
cooked pasta (about 8 oz)


Chop onion and saute in olive oil until clear.  Add some butter and the minced garlic.  Add shrimp, bacon and a handful of shredded Parmesan cheese and season with salt/pepper (may want to add a bit more olive oil and/or butter) and cook until the shrimp is done (just a few minutes).  Toss in with the pasta and add olive oil as needed so the pasta isn't dry.
