Tortellini with Walnut & Mascarpone Sauce...

So I had a massive math error on this one when I was originally figuring it out.  I remember thinking at the time that it didn't sound quite right (but it was late and I was tired, so alas), so I sat down and entered everything into CalorieKing.com again today before making it.  Sure enough, I miscalculated on the walnuts pretty substatially...I'm not sure how, but I was definitely off.  Sooooo...contrary to the menu plan, this dish will now be SIX servings instead of four and 511 calories instead of 470...whoops!  :)  Anyway, it seemed to have all worked out as far as portion size, etc., so it's all good.  I think I stumbled on this recipe on FoodGawker, although it could have been Pinterest...it's all starting to blur together this month.  The original is found on Kayotic Kitchen (which will be used for THREE recipes this month, if you can believe it...she's got some good looking stuff on there!).  The whole "Kayotic" thing was sort of ironic, since once I got into the recipe, there were some dramatically different measurements reflected in the ingredients list than were referenced in the actual body of the recipe.  I went with whatever looked right to me and/or what I actually had on hand.  I would normally have used a spinach tortellini, but again, as my sister will be in town, I skipped the spinach in order to avoid an accidental trip to the ER.  I also doubled the recipe (the measurements I actually used are reflected in my recipe below), as the original recipe was intended to be a side dish, and I'm making entree portions.  Anyway, here we go:

Tortellini with Walnut & Mascarpone Sauce
6 Servings, 511 Calories each

Ingredients
- 1 med. onion, diced
- 2 cloves garlic, minced
- 3 oz. walnuts
- 2 - 9oz. pkg. tortellini
- 2 oz. shredded parmesan
- 1 T. olive oil
- Salt & Pepper, to taste
- Flat leaf parsley, to taste

Directions
Toast walnuts in a dry skillet for a few minutes to bring out the flavor, and then run through food processor/chopper; set aside.  Mix together mascarpone, parmesan, and parsley; set aside.  Cook pasta according to package directions (don't forget to salt the water).  While pasta is cooking, heat oil in a skillet to med/med-high.  Add onions and garlic and cook until tender (I browned mine a little, which I hadn't intended to do, but I got distracted for a couple minutes by a phonecall, and let them go a tiny bit too long...either way, it'll be fine).  Add mascarpone mixture, and stir until melted and combined with onions/garlic.  Stir in walnuts.  Mix in drained pasta and enjoy!

This looks really tasty...I tried a little bit of the sauce and really liked it.  I think the portion size will be fine...I was a little worried when I made it into two extra servings to keep the calories semi-reasonable, but it looks like it'll be plenty.  I'll let ya know how it all turns out :)
