How do you divide the Muzzarella pizza into 7 parts?

The https://g.co/doodle/xds69wp in my region is about dividing pizzas into different numbers of slices. I am stuck at level 5 where you have a to divide a Muzzarella pizza into 7 slices using at most 3 cuts. How do I do that?
I think I need to get to the state where I have 1+3 slices and then double the 3 to get 1+3+3=7 but I don't know how.

This solution worked for me, see picture:
