Porridge with peanut butter, banana, and frozen berries
Overnight oats, baked oats...
Bagel (or other substantial bread-based product) with peanut butter and banana
Muesli and/or granola with yoghurt and fruit
Smoothie bowl with granola and all the other toppings
Breakfast protein smoothie (blend in oats, protein powder, yoghurt, chia seeds, peanut butter etc. in with your fruit)
Pancakes! Loads of recipes online, banana and oat pancakes (topped with bananas and peanut butter/nutella) are very nice
Toast (sourdough would be especially nice) with eggs (scrambled, poached, or however else you like them) and tomatoes/mushrooms/avocado/spinach
Shakshouka and toast/bread (for dipping)
Wraps with eggs, veg, maybe some cheese (maybe black beans as well – breakfast burrito type thing)
Technically anything that is your first meal of the day is "breakfast", and I don't see why some foods should be labelled as "breakfast" foods and others as "non-breakfast" foods; you did ask for
original so I will also add pesto pasta and cottage pie to the list
