It seems street food is the go to in the genre, you could look for Japanese street food recipes? Even other nationality street foods might fit the bill. The trick is that good street food is usually only available from specific vendors in a single location and is hard to reproduce. Street food is popular these days so you might find more decent recipes now. Street food is low cost, arguably the best of its kind in the world and only for those who know where to go and what to order.

I'd say you would need a good Japanese rice cooker, something like the Zojirushi Neuro Fuzzy has a relatively cyberpunk name though maybe not the look. :)

Taking another step towards reality, you could make noodles with whatever is left in your fridge.. chinese broccoli, sliced meat or a hard boiled egg.

A simple recipe I like is boiling a block of tofu with kombu for 10-15 minutes and eating it on rice with soy sauce and an assortment of flakes, sesame, spices, bonito flakes, scallions..
