There's something about Italian food that gives me that 'comfort' feeling. It's hearty, filling, and always hits the spot. Of course, it also typically includes gluten, grains, or cheese of some sort that's going to make me feel guilty (not to mention lethargic & bloated) the next day.
In comes one of my favorite dishes I've been making forever: "Sausage & Peppers". It's an Italian-American classic that is obviously delicious on toasted bread with melted cheese on top, but is equally tasty eaten straight from the bowl.
