Here's a site that can help you.
Soylent. Doesn't get any easier than that! Lol.
This site can help you.
You can make Breakfast burritos ahead and pop them in the microwave in the morning. Ready in a minute. Put whatever you like in them. Really easy to make and lots better than the frozen ones you buy
Smoothie; have smaller bags of frozen bananas + berries/veg ready in the freezer. In the morning, take the bag out, top with water or whatever milk you like, add a scoop of whey protein powder and whiz up.
I add LSA, Flaxseed, psyllium husks, ground oats to bulk the fibre up.
I've also recently discovered preparing the night before in a jar oats, almond or coconut or both milk, fruit, chia seeds, flax seeds and some honey or 100%maple sirup. It's high in fiber and not very sweet.
Scrambled eggs (optional: turmeric, salt, pepper) is super quick and delicious.
I'll either have egg cupcakes, hard boiled eggs or a breakfast essentials shake. Egg muffins are easy you just mix whatever you would want in an omelette and pour it into a cupcake tray and bake them. You can have 1 or 2 for every day of the week! Breakfast essentials either come pre-mixed or you just add milk.
You can pre-cook steel cut oatmeal - either on the stove or in a crock pot (lots of recipes on-line) cook once and heat a serving each morning. If you prefer a cold breakfast make up a healthy muesli mix and soak it overnight to eat in the morning.
