Hello!
I use ninja nutri bullet: frozen fruits (bananas, any type of berries, etc). Ofet mix 2 to 1 with protein whey (so you get flavour from protein whey, less calories, more protein and there is a variety of flavours. Matcha powder - subtle but nice. Apples and cinnamon for apple crumble taste.Blend banana, 2 eggs, one scoop of milk, add milk until right consistency and fry pancackes on coconut oil (YAM!). I never get bored to be honest, especially when use different flavours of whey protein, like salted caramel or rhubarb crumble.
