It is a challenge indeed. Some suggestions:

-- Whey protein powder: Amazon.com Nutricost Whey Protein

The package says take 1 scoop a day, but my registered dietitian OK'd my using it twice a day. I do not use it everyday, but I will make it a goal to increase protein.

I normally use it in a smoothie. I put some frozen raspberries into the blender, add 2 tbsp chia seeds, 2 tbsp flax seed that I first grind in a spice grinder, some plain kefir, some plain nut milk (just nuts and water without any additives, from Nuts.com), and a scoop of this powder. It is palatable enough. I wish I could add more raspberries but the dietitian said not to.

I also mix it with farmers' cheese and you can try mixing it with cottage cheese. Maybe not even the whole scoop but half of it. It is worth experimenting with.

-- Milk: switch to Fairlife ultrafiltered milk (advice from an RD). It has more protein than usual milk with half as much sugar and carbs. It tastes just the same. It is more expensive, but the price is worth the nutritional benefit of it.

-- Greek yogurt is high in protein. Icelandic yogurt called Skyr is also high and sometimes even higher. With them, it pays to read the labels at the grocery stores to pick the one with the most protein per serving. There is usually a spread of several grams among brands. Picking the highest protein content brand typically does not result in your consuming any more calories.

-- For my post workout drink, I use Fairlife protein chocolate shake. It has 26 g of protein per serving and is delicious chilled. I buy them in bulk from Amazon. Here is the link: Amazon.com Core Power Protein Shake Chocolate
It is also available in vanilla which I have not tried and in strawberry banana which I have tried and found artificially tasting.

-- Do you not eat eggs at all?
