hello Nina, welcome

here is a page that might spark some ideas for you. Not vegan, but the vegetarian page is interesting.

and a good place to call for all things Breakfast is the step one list. Its found via make connections top right. let us know if you find it.

as for your shake questions I have not tried it, so cannot answer the 'edible' part But its good fun to layer or as we say 'stack' proteins together so if it turns out not that edible after all then thats another option. Have fun experimenting!

I used to have uncooked oats in my shake as I loved the texture. But I have read of using cooked, have a play

meanwhile, well done you on working out your protein grams and thinking on how to do it. So glad you got in touch.
