Look what I found in the camping section of a discount store where I usually buy my stuff.
Stanley Steel Cooker and Nesting Cups for $14.95. Made of stainless steel, pot top section diameter is 3.75″ while bottom edge is 3.25″, pot height (with lid) is 6″ and weighs 13.6 oz including the 2 single walled plastic nesting cups. Pot capacity is 24 fl. oz.
The pot handle locks into the lid. The lid has a foldable plastic handle.
The 2 plastic cups weighs 5.75 oz and if you're anxious about weight you can leave them behind and just use the pot as a cup. Then you can use the space to store your stove, fuel, windscreen etc. so you have a complete cooking kit.
