I had this tonight with a big bowl of beef barley soup and it was quite enough for dinner. You can have this with a salad, with tomato rice, with almost anything and it will be a meal. It will also be a cheap meal that you can dress up or down.
Bake the potato and let it cool. while it is cooling saute a few chopped onions with a little garlic and thyme. Go to your fridge and see what leftovers or scraps you have to go into this dish. I found a little bacon, a couple of slices of ham, tomatoes, frozen peas and carrots and onions.
Cook what ever you find in with the onions and then add some crushed garlic. For vegetarians you can use scallions, chopped mushrooms, sweet peppers and the like,
Mix this in with the potato and crush the mixture in a bowl. Fill the empty skins with this mix and cover with cheese. finish in the oven and under the grill.
This is a full meal with a bowl of soup or a tossed salad.
