House spider eating onion?

Observation - House spider eating onion? - UK and Ireland. Description: I saw this house spider apparently eating a piece of dropped, cooked, onion on my kitchen floor. Is this possible? I thought they only predated other animals. Perhaps if it was a choice between starving and death?
