Here's a hearty breakfast that is great for camping or the dead of winter.
4 med potatoes, peeled and cubed
3 cloves of garlic chopped
1/2 medium onion chopped
4 Tbsp butter
Over medium heat add 2 tbsp of the butter to a small frying pan and saute the onions and garlic together.
Once the onions become clear, add the potatoes and the rest of the butter to the pan and cook until the potatoes are tender.
You can probably substitute margarine or a low fat substitute for this if you're not comfortable with real butter.
