Using oatmeal for compost

Incredibly random question for someone who's never posted on the forum before, but recently got a product recall for HEAPS of porridge as there was a mouse contamination at the factory, so it's unfit for human consumption.

It was an Internet purchase so I couldn't physically return it to a store so am literally just sitting on it, is there any kind of gardening application?

I am a live in carer for a 94 year old, and she has a garden in two parts - one part cute with the lawn and the roses and other flowers and a rockery, and the other larger part a mostly re-wilded lot with a couple of patches of rhubarb and strawberries and some fruit trees, and we'll grow runner beans there later in the summer.

Do I just bag up all of this potentially mousey porridge and throw it in the bin as instructed, or is there something I can actually DO with it?
