I made some bread today using the only yeast I could find, 1 x 7g sachet in Asda, which was one out of a multipack that they gave me FOC. Amazon had a 125g tub on prime, great thought I, I'll order that, placed the order...delivery anticipated 14th April. 
You are an engineer; use your imagination!
Simplest form of edible flour (i.e. bread) is to mix flour with water to a consistency like double cream. Optionally add an egg or use some form of milk instead of water.
Pour sufficient into a hot frying pan, and swirl around to create a ~1mm thick layer. Cook for a minute or two. Use spatula to turn over (flipping the pan is for amateurs!). And there you have a tortilla or pancake, depending on your preference.
Add filling of your choice, from lemon+sugar, to tinned mackerel in tomato sauce, to whatever is left over in the freezer.
That was the staple breakfast I gave to my daughter for years. Quick, easy, simple, malleable, interesting: what's not to like.
