Agree with the others. Pulverizing the left over veggies to a mush and then sending down the sink to a flat tank where they can lay on the bottom and build up and be a problem is a BAD IDEA. Scratch it from your (and your wife's) consideration list and use it as an excuse to carry the cutting board outside to a table and throw the chopped leftovers in a garbage can. This will get you outside more, give you some walking to do the dumpter after dinner (to prevent the leftovers from drawing critters) and most importantly, prevent you from having to work on a nasty, clogged gray tank that has decomposing food that smells almost as bad as the black tank.
