Two other friends and I flew to Southern California to enjoy a few days with a girlfriend who moved closer to her grandkids—her son needed help and she rose to the challenge. I offered to cook all the meals during the visit because I've learned that I won't get decent food (or any food... hello, breakfast is the most important meal of the day) unless I step up. Thrilled about having me cook for them, they were eager to see what and how I cooked.
It's just easier for me to cook than give the cook instruction for my eating lifestyle. In this case, the cook was primarily my friend's husband and he wanted to learn more about eating healthier.
