get the pastels cooking

1) to go out and "get the ball rolling", so to speak, with a certain physical activity

2) when one is "rusty" at a certain sport and they want to get back into shape or return to the state in which they previously performed in a consistent manner due to an upcoming event in which that person or persons will compete at said sport/activity
3) to heat up and eat one's artistic supplies

Ay boys, lax season is right around the corner so we gon' go out this afternoon and get the pastels cooking

Wow, Grayson is pretty good considering he hasn't played in a while; he musta got them pastels cooking awhile ago
