Eating a plant-based diet can be challenging. Maybe the best advice I can give you is that its like a hundred times better than the alternative.
The animal cruelty issue is what keeps vegans vegan. They know how much cruelty went into that egg. How much pain and suffering was required to make that gallon of milk. Vegans can't condone an industry that kills billions of animals a year because they taste good.
A lot of people are going plant-based just because of health concerns. Sure that hamburger smells good. and with that do you wish a side of satins? or should we book your colectomy right now?
Scientist not only are convinced that man-made climate change is real but that it an existential threat to mankind. The fastest, easiest, cheapest way you can personally cut your carbon footprint is to go vegan.
So what if you can't find the tastiest vegan foods. You can't seriously consider the taste of your food to be more important than animal lives, your personal health, not to mention the survival of mankind.
Fortunately making delicious healthy plant-based meals is probably not as difficult as you think. If you go to the library you will probably find a dozen or more vegan cookbooks. They even have themes now. Like easy recipes, ten-minute recipes, one-pot recipes, stir fry recipes, and Instant Pot recipes. Just check them out or sit at a table and peruse a few. Find half a dozen to try and go do your grocery shopping. Try them out and then find some more or just stick with the ones you like.
I just saw your comment. And I like stir fry too. How about this one - it's my new favorite. tofu stirfry with bell peppers, onions and spinach with teriyaki and sweet and sour sauce served on top of soba noodles mixed with soy sauce and nooch. Then topped off with everything bagel seasoning.
I also like lentil stew over mashed potatoes, Cuban black beans over rice, split pea soup, vegan chili. Try the OneGreenPlanet website for recipes.
and you can make a vegan omelet or scramble. Try googling for a recipe.
