Roasted Beet, Quinoa, Chicken, and Arugula Salad Jars

These hearty, anti-inflammatory salad jars bring together earthy roasted beets, peppery baby arugula, and tender roasted chicken in a simple balsamic vinaigrette for a deeply satisfying make-ahead lunch. Beets are a rich source of betaine, a naturally occurring compound that supports healthy methylation and liver function, while arugula provides glucosinolates and potassium to support detoxification pathways and fluid balance. Each jar contains about 32 grams of protein and 32 grams of net carbohydrates per serving. The combination of complex carbohydrates, plant fiber, and high-quality protein helps promote steady energy throughout the day. Make these in advance so you have balanced, high-protein and fiber-rich lunches prepped and ready for the week ahead. When you're ready to eat, simply dump the contents of one jar into a bowl and toss to evenly coat in the balsamic dressing.
