Preheat oven to 350
Mix eggs, cream and seasonings. Set aside.
Cook bacon on medium high heat. Once cooked, remove from pan and set aside.
Return pan to the burner and reduce heat to low. Add diced onion and cook slowly for 20 minutes for proper caramelization. (You can cook them quickly if you like but trust me when I say that caramelized onions are worth the wait). Once cooked, add kale and garlic and cook until kale is wilted.
Spray an 8inch nonstick, baking dish with oil. Line with cooked bacon, then cooked veggies, then cheese and finally the egg mixture. Top with sliced cherry tomatoes if you’d like.
Bake for 35-40 minutes or until the center is firm.
Allow to cool (quiche will shrink a little). Slice and enjoy!
