Cooking with Dog has a few simpler recipies in the older videos, like the miso ramen w/instant ramen one https://www.youtube.com/watch?v=J7fZjiLV36c

Cooking a meat is not too difficult once you learn not to fear the pan. For a big hunk of meat like cooking steak, you leave the meat in the pan and don't touch it until it's about halfway, then flip it over for the next half. Typically you might work with slices instead like in Cooking with Dog for some kinda stirfry. That order is put meat in pan, you can stir it around a bit, wait until it's white looking. If it's a little thicker slice, add a few minutes in the pan after it's gone white. If you want to check if it's ready, you can always cut the thickest piece and check.
A helpful meat/general cooking tip is to be careful with the temperature. Hot pan is great, but a very hot pan to try and make your food cook faster actually gives you the chef less control with your food. It'd suck if your food was burnt on the bottom but not cooked on the top.
I don't honestly know how vegetarian meat-replacements work. I grew up with and mainly cook chinese food. No one in my family's vegetarian and if we want a "vegetarian" we just cook a tofu dish. I'm sorry…
As for show… let's see. I tried to get into baking recently. It's a different beast than cooking, methinks. I made some Skyrim sweetrolls and it was pretty goddamn great. Pic is the resulting sweetrolls. Please forgive the lack of proper icing placements… I have no idea how to make icing smooth.
Holy shit this is long I'm sorry. Either way I wish you best of luck! No need to be afraid, the worst thing that can happen is you learn something for the next attempt.
