Of course, it depends on one's definition of satisfaction. My father thinks a lot of food is delicious, but he won't be satisfied unless there are dead animals in it. But there are many foods he likes, which can be cooked without meat. They are equally delicious and the seasonings are good.
For example, except chicken, there is no substantial difference between fried noodles with chicken and fried noodles with vegetables. No chicken will not affect the taste of vegetables. You can also make the same explanation for curry, oven dishes, pasta and other foods. I mean, there are more vegetarians and vegans in India than Americans (eat meat or other things). Do you really think that 400 million Indians will live on a light diet?
So it's easy to make delicious food. Satisfaction is subjective. For example, my father likes eating meat. So is my brother. If my brother wants to eat chicken wings or stick John, there is absolutely no vegetarian who can satisfy his desire for chicken or junk pizza. You can substitute vegetarian food for those things that make people want to eat meat-fat, salt, calories-but you can't substitute other foods to get rid of the psychological desire for this kind of food. If I want to eat popcorn from the cinema, I want to eat popcorn from the cinema. It's not popcorn made by microwave oven, nor popcorn made by stove (is it still popular now? ), nor is it frozen bagged grocery popcorn. I want fresh cinema popcorn topped with coconut oil.
But considering fat, food richness, calories and satiety, it is not difficult. Using more olive oil or rapeseed oil in cooking can add some richness and fat to vegetables. Use canned coconut milk instead of soy milk or almond milk (or milk) in the recipe. Spaghetti and potatoes have a lot of stuffing. I don't believe anyone can tell me the difference between my fresh mashed potatoes (or most other dishes) made with vegetable milk and butter and other versions made with milk and butter.
Is it easy? As long as you can cook (basically not the level of a chef), it is not difficult. I am a simple person. I don't have many "food cabinet necessities" ... salt, pepper, garlic powder, onion powder, red pepper slices, olive oil, rapeseed oil, roasted sesame oil, soy sauce, vegetable butter and tomato sauce. 95% of the food I cook doesn't need any other seasoning except the food itself. I use a lot of fresh peppers (Serrano peppers, jalapenos), onions, garlic, mushroom oil or sun-dried tomatoes (in my oven) to flavor them. I can make 20 different, rich and satisfying dishes by mixing fresh vegetables, dried rice and beans or canned beans and tomatoes.
