Deep dish sausage please!
Sorry, CV. There is a Torah law not to
cook meat and milk together, even if YitzyS didn't eat it. Although it is only a
grama (he isn't doing the cooking, but by placing the order, he is causing it to be cooked), arguably this is also benefiting from a meat+milk combination (as I assume you would be grateful), which is also prohibited.
If you were an ingrate and didn't care that he ordered you one, it is possible that it would be permissible, but since we know you are not an ingrate, it doesn't work.
We live complicated, very precise lives, you know.
