MR: If anyone has reservations about healthy eating—let’s say your friends or family—the best thing to do is never tell them from the get-go that what they’re eating is healthy. I have a lemon curd recipe in my book that I’ll be serving the next morning for a fun brunch meal, but it’s a sneaky one as it’s super healthy. For example, the lemon "curd" sounds pretty decadent, right? Well I would never say, "Hey, guess what, guys? There’s tofu inside!" That might terrify my family. But unbeknownst to them, tofu is actually what makes it creamy without having to use raw eggs. Definitely postpone your reveal till after the fact, and then I’m sure they’ll be coming back for seconds!
Another tip: As humans we eat with our eyes first, so have fun with dressing up a healthy dish with tons of toppings—think pomegranate seeds, pumpkin seeds, cilantro, parsley, roasted tomatoes, etc. Choose ingredients that add a visual element to first entice them, then let your guests enjoy the meal, and when they’re done, reveal that it was actually a healthy dish.
