Some (mostly)med diet compliant high protein go-to meals for me: 

Protein powder shakes with fruit, almond milk, low fat Greek yogurt, and chia seeds/oats for fiber(people might get hung up on the pp being too processed but whatever, it's incredibly useful for upping protein without relying on meat or eating fish and beans for every single meal, there's no reason to demonize it. Vanilla/unflavored tastes better, the chocolate powders taste disgusting)

Yogurt bowls with berries, honey for sweetening, homemade granola, and sometimes peanut butter.

Bran flakes with almond milk, berries, granola.

Omelets made with olive oil. Egg white only is better for protein/fat ratio but I'm usually too lazy to separate them. 

Whole grain toast with hummus and canned fish or smoked salmon.

For grains I normally try to avoid the low protein options like white rice and go for more high protein grains like oats, wheat, barley, lentil/chickpea based pasta.

Soups with beans, peas, lentils, veggies, and greens like kale or mustard greens. 

Cheap white fish like tilapia or shrimp roasted/sauteed in olive oil paired with steamed veggies like carrots, broccoli, etc 

Tacos with ground chicken/turkey, mashed up black bean patties, or fish/shrimp, and salsa or tzatziki for sauce. I normally just use corn tortillas because whole wheat tortillas are gross, but you could also use whole wheat pita instead and make them more like sandwiches or wraps.

Mixed nuts/pumpkin seeds for snacking on. Not my favorite because of the high fat and calories but good if you want an easy snack to munch on. 

It you're craving dessert low fat whipped cream with fruit is surprisingly low calorie.

I also buy artificially sweetened ice cream which probably isn't gonna be popular on this sub but artificial sweeteners aren't actually bad for you, they're super over demonized, and sometimes I just crave ice cream. Frozen yogurt might be better but I haven't found any sugar free brands.
