Coconut flour muffins are super awesome (bake the recipe in a slab tin and cut in squares for super easy). Banana bread too. A lot of those things you can mix in under 15mins then shove in the oven and pull it out when the timer goes off and it's done. You can store it in the fridge and grab out for breakfasts or even make a bit a few weeks ahead and freeze, just pulling out the portions you want the night before. The coconut flour ones are great because they're full of eggs and coconut oil and are a great breakfast. Have it with some fresh fruit and you're sorted.
