Eggs are a very healthy food but eggs by themselves is not a meal.
At the very least, add in some vegetables and make an omelette. You could stir fry some bell peppers, onions, mushrooms, spinach etc and then add in the 4 eggs and make a big omelette for breakfast.
That would be a much healthier and complete breakfast then just eggs.
If you don't have access to oatmeal, can you get things like grits?
