I too need all the calories I can get in the winter, my favorite winter staples:
breakfast: veggie/ham/cheese omellett or pancakes with fruit
but if I am in a rush, I go with oatmeal or power bars
Lunch: any kind of sandwich melt- like a tuna melt, or as you mentioned grilled cheese but I like it with ham or turkey
Dinner: steak and potato dinner. Marinate steak for an hour or more with 1-2 cups of cabernet red wine, some dashes of olive oil, sprinkle brown sugar, salt and pepper and about 1 tbs butter and in a pan you can add fresh garlic, cut up green or red peppers and onion for extra flavor (prep time: 10 minutes, cook time: in a frying pan anywhere between 5-10 minutes depending on your preference)
for a spicy, hot drink:
a Spicy Mexican Hot Chocolate-
1 ounce chocolate sauce (hersheys works)
Add a small dash of Cayenne pepper
A tiny pinch of cinnamon
A few drops of Vanilla syrup (not vanilla extract)
1 cardamom seed
1 cup warm milk
I used to work at espresso bar/cafe ;-)
Vanilla and cardamom are not super important, but with all of those ingredients, it is a divine drink. It reminds me of the hot chocolate drink from the movie Chocolat
