posted the concept before. It bears repeating under the current topic of presentation. You can chop up some fruit and veggies (or buy them chopped), set out some bread, cheese, and nuts, and everyone will think you're a genius. It's all in the presentation. Whether you put out a little bit like I did here for just myself, or several boards, each with a theme, it turns snacks into a leisurely meal. It's how Mediterranean-rim countries eat during the warm summer evenings. There usually isn't dessert, just a pile of grapes or other finger fruit.
This is also a great thing to add to a barbecue gathering for vegetarians and vegans, so they don't feel left out. I wanted tuna salad, but a cup of hummus or dairy-free bean dip would be a vegan protein. It's a way to cater to a special dietary need without anyone feeling like you reluctantly made something just for one person. There are many specialty diets that can work with this concept, including paleo, diabetic, and gluten-free. Plus, it's just a generally healthy way to eat.
