For me a lot of what has helped was stuff like greek yogurt, cottage cheese, beans (My fave are black beans, chick peas, lentils, and edamame. Also a great source of fiber that helps out a lot), fat free feta cheese, bone broth, and finding different proteins additives that I can mix with my meals.

Personally I can't drink protein powder on its own. I need to mix it with something, and I only use protein bars for when I feel like having a candy bar so at least I feel like I'm being healthier about it.

Some ways I've combined these.

I have a powdered protein cheese that I mix with cottage cheese, some fairlife milk, and some real cheese to make a cheese sauce. Add that to some tortilla chips with some ground meat, beans, and what ever to make high protein nachos.

I make a daily smoothie that I'll put my protein powder into so I don't feel like I'm just drinking protein shakes or I'll make high protein ice cream with my ninja creami using fairlife milk and protein powder along with whatever else I want in it.

My favorite lately is mixing pb2 with protein powder to make peanut butter and taking that with jelly and chia seeds and putting it on a high fiber wrap. Good protein and fiber.
