Kitchen waste from a 2-person familiy (remember that meat waste
doesn't go in a compost bin) isn't on its own going to sustain 50
square yards of grass cuttings in the summer. You need a balance or
you'll end up with simple smelly mush

A few card boxes from the tons of packaging mixed in with the grass
cuttings (+ urine) will help with that. And it doesn't really matter if
it gets a bit mushy as it will rot down eventually.
