My husband likes Reubens, and my daughters love pickles and sauerkraut, so I figured they'd love this recipe. I was right! It was one of the tastiest meatloaves I've ever made. I love the little bits of cheese, and I like how the cooking of the onion/carrot, even though it's an extra step and dirties another pan, gives it a mellower flavor.
I made the meatloaf into two separate loaves and froze one for later. One loaf (half the recipe) fed my family, with second helpings for the parents.
