I like to ham it up and say "stove? let me introduce you to the BRS 3000!"
My UL brew kit (also large enough for pasta for one) is a big stainless steel mug as the pot, a mini gas, mini Bic lighter and the BRS 3000. It all nests in the mug, add a collapsible STS mug if you want. Held together with a toddlers sock. Nice, cheap, ultralight.
