Summer buffet

I make a version of this cous cous dish with all varieties of grains and herbs. It is flavorful and filling and would be great with steak or shrimp: http://food52.com/recipes/18074-herbed-couscous-with-fried-eggs

a quinoa or israeli couscous salad might be great. Some type of slaw or maybe a tomato salad (we had great tomatoes at the farmers market this week).

Tenderloin is a flavorless cut of meat, Tender juicy expensive but flavorless. Invest your time in a robust sauce, and subtle side dishes that don't compete with the meat. Also the tenderloin without a knife??? Maybe some lamb chops would make more sense? If you insist on the tenderloin try some roasted baby youkon potatoes, with lemon and fresh herbs, asparagus with a light hollandaise? vegetables in general on the grill are great for this time of year

There are some great corn salads on food52.
