Confetti Chicken Casserole

0 Preheat the oven to 350°F.
1 Add the bacon to a skillet over medium heat. Cook for about 5-7 minutes, until crisp, then remove the bacon from the pan and drain off the excess fat. 
2 Heat 1 teaspoon olive oil in a large sauté pan over medium-high heat. When hot, add the onion, peppers, and garlic. Cook, stirring occasionally, for 5 to 6 minutes, until the vegetables are wilted and slightly browned.
3 In a large bowl, stir together the onion and bell pepper mixture, corn, kale, chicken, mayo, salt, and pepper until combined.
4 Transfer the chicken mixture to a 3-quart (9x13) rectangular casserole dish, then top with the cheddar cheese and bacon.
5 Bake for 30 minutes, until the top of the casserole has browned.
6 After removing the casserole from the oven, let it cool slightly, then garnish with green onions and serve!
