If I ever had food left from a catering job that went untouched. If I brought it here, they'd accept it right?

Call first and ask . Prepared food is tricky we have a kitchen and serve meals at exact times and snacks and desserts . But we have taken party chili and added to it to make more and your food might work depending on what the item is so call and ask us :) peace and love

If ever you had untouched food left from catering , the House of Mercy will gladly except it and it will be given to it's Residents " any help given to the Homeless is considered a Blessing " Thank you

Yes food that is unopened

Yes they will accept food that is unopened

Yes they will

I've done that in the past and they were able to use it.

I'm not sure cooked food they probably wouldn't except. fresh vegetables bread etc. due to food handling issues.
