I had bought a Stanley pot ($13 at a Target, I use the plastic cups as tooth brush cup in the bathroom, and as an extra cup in the kitchen) before, but was annoyed when my plastic Nalgene couldn't nest into it. I wanted to get a stainless steel bottle though, and saw pic-related (a different picture, saw it a few years ago, similar picture). A Guyot 32 oz stainless steel water bottle ($19 on Amazon), fit perfectly inside, and allowed me to boil water inside. Then I wondered if a GSI cup could fit around the Stanley pot, and saw other people had already came to the same conclusion. I find space to be a bigger issue than weight, I never ended up weighing it. It's certainly not as heavy as a full mess kit though, but is a bit heavier than titanium equivalents. I bring a simple metal spoon from the kitchen with me, and just use my belt knife or my Opinel along side it.
Of course, this is really more for boiling water or eating oatmeal and soup, rather than for frying or the like, but it has done it's job nicely. For meat, as another anon has said, I use a stick or a skewer.
I also use a Trangia alcohol burning stove, as I was not steady-handed enough to make one out of a soda can. One day I will... The stove fits inside of a tin can that I pocked holes through, sort of like a windscreen and pot holder for my trangia. but also functions as a wood burning stove.
My kit is definitely heavier than titanium equivalents, but at a fraction of the price it works for me. Poorfag woes. Speaking of poorfagging, the tin can stove/potholder work well with a Trangia, but makes me look like a hobo when I use it.
