Help! My BIL is coming to stay with my husband and me for the next month, and he has stated that he would like to try new flavors/foods. While his mom is a great cook, she cooks non-chowhound, kid food: heavy on the meat and starch and light on the veggies. While I would like to help expand his horizons on the food frontier, I would rather not force the issue either. My first thought was to ask him what he likes and then try to liven those things up; however, I fear the list of foods that he likes will be short. So, I ask you fellow chowhounders, how would you go about introducing new flavors and foods to a 17 year old boy?
