Prepare the brown rice according to package instructions and set aside.
In a small bowl, whisk together the Greek yogurt, finely chopped basil, and lemon juice to create the dressing.
Lightly steam the broccoli florets until they are tender-crisp and bright green.
Season the chicken breast and shrimp with sea salt and black pepper.
Heat olive oil in a skillet over medium-high heat; sear the chicken for 5-6 minutes per side until cooked through, then sauté the shrimp for 2-3 minutes until pink.
Slice the cooked chicken into thin strips.
In a large bowl, combine the spinach, arugula, and kale to form a nutrient-dense base.
Top the greens with the cooked brown rice, sliced cucumber, steamed broccoli, chicken, and shrimp.
Drizzle the creamy lemon-basil yogurt dressing over the bowl before serving.
