Filling half the plate with plants isn't as hard as you think. We make it easier with salty, crispy bacon--one piece is all it takes to elevate this bountiful bowl of fruits and vegetables.
Preheat oven to 350°.
Remove white papery skin from garlic head (do not peel or separate cloves). Wrap head in foil. Arrange beets on a large sheet of foil; wrap tightly. Bake garlic and beets at 350° for 1 hour or until beets are tender; cool 10 minutes. Separate garlic cloves; squeeze to extract garlic pulp. Discard skins. Combine garlic pulp, oil, and next 5 ingredients (through pepper) in a small bowl, stirring with a whisk. Place spinach and kale in a large bowl.
Heat a medium skillet over medium heat. Add bacon; cook 5 minutes or until crisp, stirring occasionally. Increase heat to high. Stir in garlic mixture; remove from heat. Pour hot bacon mixture over kale mixture, tossing to coat.
Peel beets; discard skins. Cut beets in half. Arrange beets and oranges over kale mixture.
