I find a tiny pair of scissors to be very useful. I trim back only one part of my facial hair, the 'hitler mustache' area. It can be done quickly and easily and with care, few would notice there was anything trimmed at all. For me, it makes a world of difference when eating. I wont try to convince you further, I know Ii'm set in my ways, just wanting to say that there is an alternative to lip hair inhalation.
RE soups and stews: Leave it. Let it dry. You never know when you might need an emergency ration. Soak it in a bowl of water for a light snack or a mid-afternoon burst of energy.
