Seitan steaks aren't difficult to make with some vegan gravy of your choice (though recipes *can* become more complex, for example seitan chkn fried steak takes more time and ingredients than a basic recipe).
If you don't want to cook really, Gardein makes very convenient and convincing Fishless Filets, as well as their ...Hmmm...I think it's orange chkn, or sweet and sour chkn? Just pan fry for a few minutes and microwave the sauce on the chkn (for fishless filets, use ketchup, or malt vinegar and lemon, or whip up a simple vegan tartar sauce ) ...you can also bake both if you stay away from pan frying.
I like Tofurky kielbasa vegan sausage, for a few minutes in a cast iron pan with sourkraut, until lightly browned, can use a canola oil spray for less oil, or a dab of olive oil for richer flavor. Serve with horseradish or brown mustard (or yellow mustard w/e) ...pair up with a quick veggie or a green salad. Can also make a sandwich on bun instead.
There are some meatless crumbles out there that can easily be added to recipes, like in spaghetti sauce, lasagna or stuffed shells (with vegan cream cheese or Daiya), or mixed with sauce to make Manwiches, or whip up something with a white vegan gravy or "cream" sauce and onions and mushrooms, over pasta or potatoes.
If you are trying to avoid pre-made vegan "meats" entirely, I suggest again basic seitan steaks you can make at home easily, as well as pan fried or baked tofu with spices or marinade, and adding beans to burritos or rice dishes, and lentils to tacos and ethnic dishes. Explore Indian, Thai and/or Mediterranean food - falafel with tahini, hummus and/or babaganoush is a protein in its own right, and Indian food that has dal and spinach somewhere in the mix is good protein. Thai food is very simple to add chunks of firm tofu.
