Put the bacon into a wide, deep frying pan and cook, turning, over a medium heat until just starting to crisp. Sprinkle with 1/2 the sesame seeds, flip, then sprinkle with the remaining sesame seeds. Cook until the bacon is really crisp and the sesame seeds have toasted, then remove onto a plate. Tip the pak choi, sugar snap peas and baby corn into the same pan, and toss for 1 minute in the bacon fat. Add the ramen noodles, flavour sachets and recommended amount of water, and simmer according to pack instructions. Then add the soy sauce.
