Far and away, the Houston Food Bank is my favorite charity.
They achieve so much, for so many, in terms of distributing food to other organizations that then put the food in the hands of those most in need.
The amount of food each $1 donate puts on the table is amazing, have a look at their website for yourself.

The Houston Food Bank works very hard to reduce admin costs to increase the amount of service they can provide to those who are hungry in Houston. They are efficient and well-organized. Their main facility is awesome and a fun place to volunteer. I think this is a great organization that is in need for many, many more volunteers. The more volunteers they have the more they're able to use their funds to feed people rather than paying employees. I highly recommend this organization for both donations and volunteer hours.

I have volunteered at this organization with my church group as well as having been a donor for years. They are a highly efficient organization, their warehouses are tidy and orderly and the food is well accounted for. They serve numerous smaller food banks around the city and benefit the donors providing large in-kind donations (grocery stores,etc) by accepting the large donations and re-distributing it to where it is needed at the time, as opposed to a small pantry getting a large donation that it can't use efficiently (500 boxes of beans). It is a great organization and serves the neighbors and friends in Houston that need a bit of help to make it to the next month.
