This is an all-in-one dish! The chicken is very straightforward, so the beet puree can be the star of the show. For a more subtle beet flavor, add a steamed, fork-tender potato to the puree after you’ve blended the other ingredients. A Food Fight, Round 4 Recipe
Heat one tablespoon of oil in a heavy-bottomed frying pan. Sauté onions until lightly browned, about 15 minutes.
Add diced apple and cook until very soft, another 10 minutes. Season with one teaspoon of salt and 1/4 teaspoon of pepper. Transfer to a blender or a mixing bowl. Add beets and chicken stock, and blend until very smooth. Taste and season.
Heat remaining tablespoon of oil in the same frying pan over medium-low heat. Season chicken well.
Cook in a single layer, skin side down, until brown and very crispy, for about 15 minutes. Flip and cook until done, about another 10 minutes. (If cooking in batches, store chicken in a warm oven, skin side up.)
Remove chicken from the frying pan and add the spinach to the pan. Season with salt and pepper and cook until just wilted and still bright green, about two minutes.
Spoon beet puree into a shallow bowl or dish, and lay spinach alongside it. Arrange the chicken on top.
