Chicago-based entrepreneur Luke Saunders' vision of an efficient, affordable, and wholesome lunch source has taken life in sleek vending machines fringed with live greenery. These specially designed kiosks planted in office buildings and food courts in downtown Chicago represent Farmer's Fridge, the 29-year-old founder's initiative "to make healthy food more accessible." Each machine offers a variety of hearty salads made fresh each day with produce from local farms and costing between $5 and $8.
