When they were kids, my husband's cousin once complained to their Granny that "there's too much LOAF in this meatloaf!" Can you relate? I think he had the right idea, and stopped using fillers decades ago. This exceptionally flavorful and easy meat loaf is a terrific treat hot or cold, and there's barely a carb anywhere, if you care. Now that we're watching sodium, I make a copycat Lipton onion mix without salt.
The spinach provides the visual interest, marbled throughout. Serve it with mashed potatoes or cauliflower (prepared just like mashed potatoes, and throw in a little more of that cream cheese while you're at it).
Preheat oven to 350. Nuke a 10 oz box of frozen spinach, but don't drain it. When it's almost done ( maybe around 3-4 minutes left) add 6 oz cubed cream cheese or mascarpone, stir, and nuke for another minute or so. Remove, and stir well to incorporate the cream cheese. Nuke again for a few seconds if necessary. Let cool briefly, then mix with 2 lbs ground chuck, 1 envelope Lipton dry onion soup mix, 1 egg. Mix well. Form into a loaf shape in the middle of a low, jellyroll - type pan (so the sides brown well). Bake about 60 minutes, til done in the center.
A nice, firm texture means it slices beautifully, so it's perfect for cold sandwiches.
