The reality star shared an Instagram late Thursday of a meal made by girlfriend Blac Chyna, who also posted the picture of the asparagus, carrots and cornish hen with the caption, "Cooking is love made visible."
Chyna, 27, has been helping Kardashian, 28, get fit after hid from the spotlight for two years following a battle with depression and massive weight gain.
On videos posted to her Instagram account @cookingwithchyna, she showed fans how she prepared the delicious-looking dinner.
Chyna's relationship with Kardashian has caused some tension in his famous family, as she was engaged to and shares a child with rapper Tyga, who's now dating Kardashian's sister Kylie Jenner.

But Kardashian's friend French Montana – his sister Khloé Kardashian's ex – recently told PEOPLE he supports the couple.
""I love the energy that Rob is in," the 31-year-old rapper said at this week's premiere of The Perfect Match. "As long as somebody is happy doing what they're doing and working out, having a lot of energy, I love that. It's the best years of his life, why would you stop that?"
