Kale pesto is prepared in a blender before it's baked into this yummy dish.
To a blender, add the kale, lemon juice, salt, pepper, walnuts and garlic and pulse a few times until combined. Slowly drizzle in the oil while continuing to blend until smooth or desired consistency. Remove pesto to a bowl and stir in the cheese. Set aside.
Preheat oven to 350° F.
Heat oil in a large sauté pan. Add chicken, garlic powder, cumin, salt, pepper and onion. Cook until chicken is lightly browned. Stir in 1 cup of kale pesto and set aside.
In a large bowl, whisk together the milk, half and half, eggs and cheeses.
Butter a large baking dish and layer in half the bread cubes, half the chicken mixture and half the liquid mixture. Repeat, making sure all is covered with the liquid.
Bake the strata for 45 minutes.
