Sorry to hear about your diagnosis.
I eat fairly high protein (120g-150g a day), typically I might have:
Oats with 10g protein powder, milk, Fage (slightly better than Skyr as has good bacteria which Skyr does not, even better would be Yeo Valley organic super thick yoghurt- I ate Yeo Valley for years then went to Fage but switched back as I definitely felt happier in my gut on Yeo Valley!), pumpkin seeds, pea or almond milk.
I then have a second breakfast of scrambled eggs, usually 1 large egg, after I have scrambled them I mix in 70-100g cottage cheese. Recently been adding flaked cooked salmon. Might try tuna. Often have it on seeded (more protein in seeded) toast or with homemade baked beans. Mushrooms and brocolli are higher protein veg so have those with it too.
Snack wise, favourites are apple and peanut butter, or pear and cottage cheese, more yoghurt.
Lunches and dinners I have chicken, salmon, tuna, ham, mackarel seabass, prawns, 5% mince beef, steak, carbs are usually quinoa or beans/lentils, brown rice. Sometimes pea pasta. I eat a tonne of greens as find that pretty essential to digest protein.
I try to eat the minumum 45g of protein by midday as I am less likely to snack and also my brain functions better.
I use a pea protein to make a smoothie, the one I use is actually Fast800 as it has only a few ingredients. It's not really necessary to have protein shakes unless weight training though and wanting particularly high protein.
