We’re talking cheap here. Another was noodles. Don’t just boil them in the crappy sachet they come with! Optimise it. Brown off some roughy cut onions, add some peas and/or some rough-cut veg and even some tuna and some soya sauce. Then add half the sachet (you don’t need all of it now) and then the boiled water and add the noodles - makes a kind of wanton/ramen kind of dish…
