I made this tonight, and thought it had a good cold-weather comfort food feel to it:
S/l b/l chicken breast, cut crosswise into 1/2" thick medallions
Heat a drizzle of olive oil in a skillet, brown the chicken medallions on both sides
Cover with black beans (I used a 1.5 cup container of frozen home-cooked beans, but canned would work with a sprinkle of cumin added), simmer until the chicken is cooked through.
Serve over brown rice, top with salsa and sour cream if desired.
Other winter favorites: any kind of soup, beef stroganoff, Mac n cheese, scalloped potatoes, Swedish meatballs, pot roast.
