Preheat the oven to 375°. Grease a 8 by 8 inch dish or 2 9 by 5 inch loaf pans.
Process goat cheese, herbs, and spinach in a food processor or bowl, adding cream or milk as needed to make mixture spreadable.
Assemble lasagna by layering ingredients in following order: spaghetti sauce, grated Parmesan cheese, noodles (overlap noodles by ½ inch), herb goat cheese mixture. Repeat starting again with the first layer.
Cover dish with aluminum foil and bake until bubbly on top (20-30 minutes for cooked pasta, 45-50 minutes for dry pasta). Remove foil for the last 15 minutes of baking.
Remove from oven and let stand for 10-15 minutes before serving.
If you would like you can make the spaghetti sauce recipe above with Hot Italian Sausage. Due to the very rich flavor of the goat cheese you can use a stronger flavor like this and the goat cheese won't get lost.Of course, if you want this to be vegetarian, leave out the meat and add lots of delicious veggies like sautéed mushrooms and spinach. You could also add cooked, thinly sliced veggies like butternut squash, eggplant, or zucchini.
