Penne Pasta Dinner

I got this recipe from here, but, as usual, made some alterations. It was really good. It's so good you might want to lick your plate. Or somebody else's plate.

1 tablespoon olive oil
1 onion, minced
salt
1 pound ground beef
3 garlic cloves, minced
1/2 cup sundried tomatoes, rinsed and chopped fine
16 ounces penne pasta

2-1/2 cups chicken broth
1/2 cup heavy cream
1 (5 ounce) bag spinach
1/2 cup Parmesan cheese
pepper

Heat the oil in a bit pot over medium heat until simmering. Add the onion and 1/2 teaspoon salt and cook until softened, about 5 minutes.  Stir in the ground beef and cook.  Stir in the garlic. Add the tomatoes and (dry) pasta. Pour the broth and cream over the pasta. Cover and bring to a boil. Reduce the heat to medium low and continue to simmer, stirring occasionally, until the pasta is tender, about 10 minutes.  Stir in the spinach a handful at a time and cook until wilted, about two minutes. Stir in the Parmesan cheese and season with salt and pepper to taste.
