We have come up with a new idea - pita bread without a pocket in it.
The way pita bread is usually made there is a pocket in which you can stuff things like falafel. T
In this case, there would not be an empty space or pocket in the bread. But it would be the same bread. You could dig out your own hole and put falafel in it.
The way this is different from, say, a whole rye bread, is that rye bread is not strong - if you dig out the inside it will collapse. Pita bread is stronger and you can make your own pocket.
This way you get more bread but you also can put falafel or anything else in a pocketb after yiou eat a little bread.
