Catra watches with some mild performative disinterest. She knows how to use a knife! Just... not for this. When she's finally given the knife and charge of the mushrooms and onions, she sets to work. Interestingly, despite that disinterest, she takes a lot of care with the assigned task. When she starts, she's verrrry slow and careful, trying to make sure that everything is close to the same size and constantly eyeing the results she gets. If she keeps at that pace, this might take a while.
