Well, PD, there are many sauces that I pair with pasta. Yes, I could write many recipes hubs.... but I don't have that much time since I'm in the kitchen cooking! :D
With you, I will share this special one, which can also be used as a warm salad dressing:
1 onion (sweet is the best)
1/4 c. mayonnaise
1 tbsp. honey
1/4 c. cold water
1/2 c. bacon (cooked until soft, almost crisp, crumbled or cut into small bits)
In a pan, slowly cook the onions. Allow them to sweat and caramlize. In a second, warm pan, add the mayonnaise. As it begins to warm, add the honey. Allow this mixture to blend. Add the caramlized onions. Add the salt and pepper. Stir often. Add the cold water. The mixture will separate. Bring the mixture up to a simmer. Allow the water to simmer off but keep stirring. When it is thickened, add the bacon. Season to your taste.
Mix this with cooked pasta, adding grated cheese such as parmesan cheese. You can also add this to a spinach salad.
** you may have to tinker with the recipe a bit -- I actually don't measure my ingredients (ever!) but, the amounts are in the right proportion. :)
