@mart - This one is for you! It's very quick to make, you can add or subtract whatever toppings you like. Doesn't require any special skills. It is what cadets in the military also make for themselves, (sometimes). Because you can pack it up and take it with you anywhere - Also people who stay on the road for long hours prefer this type of meal as well... Nowadays however it's a favorite with very lazy computer programmers, keyboard worriers, spammers, and trolls all over the internet. You basically take a slice of bread. How many is up to you. It can be white bread, or brown - Whatever is your preference. I am right now just using green chilies and tomatoes as the topping. You can add whatever you like, there really is no rule here. So anything goes! If you are going to use a regular oven, then no need to toast the bread. But if you'll be using a microwave. Then you need to toast it - Exactly how much, is again totally up to you. Next you spread some ketchup on one side of the bread. Sometimes I also spread a little ginger and garlic paste, other times a little bar-b-que sauce with Tabasco - Basically spread whatever you think will taste good as the base sauce of your pizza topping. After this put whatever toppings you like. Mushrooms, cut sausages, salami, anything you desire - I myself am just using green chilies and tomatoes, (as chilis actually have more vitamin C then oranges). And tomatoes have calcium also. So together they make for the perfect meal to heal bone. Anyway, next you put a slice of cheese. What type, is also up to you. But since cheese is a milk product, it too has calcium in it - Vitamin C of course helps all this calcium stick to the bone. So any injury to the bone will heal faster with the this type of food. Next you put it in your oven, or the microwave. However bread needs to be toasted beforehand if you are going to use a microwave. Otherwise the bread will become very soggy. Once it is done, you can eat it right now. Or store it in the refrigerator, (it has a very long shelf life) - You can pack it for a journey also. I suggest that you make at least 30 to 50 of them in one go. Then keep eating them whenever you feel like during the entire week. Making this is e super very quick too, (you are literally done in a few minutes), and you don't need the use of both hands when it comes to eating it. There are hundreds of variations of this on YouTube.
