Place the chicken breast in a small saucepan and cover with the chicken bone broth.
Bring the broth to a very gentle simmer over medium heat, then reduce heat to low, cover, and poach for 12-15 minutes until the internal temperature reaches 165 degrees Fahrenheit.
While the chicken poaches, prepare the vegetables by slicing the carrots into rounds and the zucchini into half-moons.
Place a steamer basket over a pot of boiling water and add the broccoli, carrots, and zucchini.
Cover and steam the vegetables for 5-7 minutes until they are fork-tender but still vibrant in color.
In a small bowl, whisk together the extra virgin olive oil, fresh lemon juice, sea salt, black pepper, and fresh thyme to create the dressing.
Remove the chicken from the poaching liquid and slice it into thin strips.
Plate the steamed vegetables alongside the poached chicken and drizzle the lemon-herb dressing over everything before serving.
