Using the chicken broth instead of water, cook the farro according to package directions.
While farro cooks, heat 1 tbsp of ghee or butter in a large skillet over medium high heat.
Add mushrooms and carrots, and cook until moisture releases and evaporates and they are nicely browned, 13-15 minutes. DO NOT SALT YET!
Once the mushrooms and carrots have nice color on them, add the additional 1 tbsp of ghee or butter, garlic and shallot, and cook 1-2 minutes until fragrant.
Add thyme, marjoram, salt and pepper, stir to combine and cook for an additional 1-2 minutes.
Add a splash of sherry vinegar, and stir to combine.
Add spinach, and stir to combine until just wilted, 1-2 minutes.
By this point, your farro should be cooked and all the broth cooked down. Add the farro to your vegetables and fold in gently to combine.
Divide between bowls, top with chopped walnuts and a drizzle of the zesty aioli. Enjoy!
