If you offer two sides, often the meat gets hit very hard and the sides do not. The exception being mac-n-cheese. Most of the times that I have done tri-tip and chicken, I have been asked to provide beans, salsa and slaw. I end up with lots of beans and slaw, and people asking about more meat.
If there is a table with several sides, then people tend to fill up a little more mindlessly, especially if there are things like little sausages, potato salad, mac-n-cheese etc...you can then use less meat. If I am starting a meal off, I like to throw smoked sausage and chips and salsa out there, start filling people a bit. If you just do two sides and meat, people really chow on the meat, often completely ignoring the beans.
the meat thermometer was so far past the top reading, it read Taylor
"perhaps...but then again...maybe not..."
