For veggies, I usually get frozen mixed veggies, it's more varied and some even have mushrooms mixed in there making them very tasty. Or I cook some tomato-based sauce.

For protein, I mostly eat Skyr and Tofu. Eggs, nuts and lentils also have good protein content, but they have other macros as well.

Unless you're doing some aggressive 1000kcal deficit every day, there's also plenty of space for "normal" meals in each day. Just do the math for the macros you need to eat for your goal. I don't think eating only veggies + protein is a good idea long term.
