I call this my weeknight meat loaf because I tend to make it midweek to get us to the weekend. Meat loaf is easy and delicious – just allow a bit of time for some prep for making bacon and sautéing onion and garlic. After that it's pretty much a one-bowl wonder. Cold meat loaf on rye (with mustard!) travels well to school, work or picnics to the park. This will make two loaves.
