I put the seasoning power in the Tupperware box and two instant noodle bricks, then I add just enough water to cover the noodles. Then I put the Tupperware box with noodles in the microwave oven for 10 minutes. The noodles come out perfect and I don't need to break them up into bits. Then I mix the noodles with plain white rice with no seasoning at all; I get a perfect meal for 3 that cost less than £1. You could also top off the instant noodles with frozen vegetables, very nice.
I wonder if there is stoneware cooking tray with the same dimensions as the Tupperware box. That would be perfect. Then I could put it in a conventional oven and stack it with other things without using much energy. I would cook the noodles and jacket potatoes together.
Someone at my work place has Bombay Bad boy flavoured pot noodles for lunch. I tried those instant noodles once, it burnt both ends 😆. I thought it was just a flavour. It was really spicy.
