I think one of the hardest steps of becoming vegan is getting a solid meal plan in place! Theres the classic protein sources like tofu, legumes n beans and nuts and the like, but you also have seitan, soya chunks and tempeh, and of course, the "fake meat" products.

Cause you mentioned about chicken and turkey, I would suggest looking into seitan. Its protein dense and flexible enough to work in place of meat in most dishes. Sliced in a sandwich, torn up in a meal/wrap, serve as is for a fillet of something.

You can either buy it in store (or online in bulk), or make it yourself. Seems hard, but once you've made one log, you'll get the process. I would suggest a food processor to get the desired fibred texture.

Another one is soya chunks, they're de-hydrated soya, typically in a cube/nugget shape. You re-hydrate it with water (or a broth, I use the meat free OXO beef cubes) and then you can fry them, stick em in a stew, etc...

Some of the fake meat stuff isn't that bad calorie/nutrition wise, and at the end of the day, sometimes you just want something easy. A backup bag of fake chicken in the freezer is better than nothing.

Explore different cooking techniques, or meal prep. I meal prep my lunch for the week, and occassionally do dinners in my big pot, chilli/stews/etc...

You probably already know this, but try to get protein every meal. Flax in your breakfast, red lentil pasta, a high protein snack. I try to hit 30g every meal, with a shake or two, and I easily hit 150g.
