Fill in curves shape

I am looking for any creative answers here. I am trying to fill in a section between lots of disconnected curves. Some are their own objects, some are in one object but using a bevel shape to make a line instead of a fill. I just want black in the big middle section but not to fill the circles. It can be its own object, it can be a mesh, it can be grease pencil, it can be curves. I’d love something really simple and fast.
I have been making a plane and extruding points around but it takes like 10 minutes :frowning:
