Very easy to make, and very yummy! This was a big hit with my boyfriend, even though he's a steak and potatoes kind of guy. I took this from Diana Rattray at About.com: Your guide to Southern Cuisine, and substituted tomatoes for mushrooms.
I took this recipe from TLC's "Take Home Chef" show and website and omitted the almonds because I'm not a big fan. These are easy and tasty, but making them does involve a bit of a mess (although that's part of the fun, isn't it?)
easy to make, and tastes like you put a lot of effort into it. I found the recipe in the Chicago Sun-Times, and modified it a little. You can easily substitute some other kind of pasta for the penne, and add or subtract other ingredients. Adding meat would make it a more complete meal, but it's pretty filling without.
