People want to be healthy but fail to invest time in the art of cooking.
In Western countries like France, Sweden, or the U.S, less than 6 hours weekly are dedicated to the activity in average, and ready meals is a billion dollars industry that keeps growing.
Cooking isn't just good for your health. It'll load up your wallet, and it will also teach you time management skills. More importantly, it'll bring you closer to reality: what is in-season, where does the stuff you're eating comes from, etc.
As a good friend of mine once said: good cooking is not about expensive food, it's about bringing out the flavors of simple ingredients. Take an omelet for example: it's all about the way you bake it. Add salt, pepper, potatoes, and you obtain a Spanish tortilla. Put everything in between two slices of whole wheat bread and add some greens. It's delicious, it took less than 15 minutes to cook (even less if you have frozen potato dices), and it's balanced. It's also incredibly cheap.
There are tons of similar recipes you can cook in bulk to reduce the time you spend in the kitchen without sacrificing your well-being. I cooked a bean curry today. Two minutes for the sour cream curry sauce, and the kidney beans were pre-cooked. I just had to wait 45 minutes for my three portions of brown rice while writing this post.
If you're feeling lazy, it's easy to cook portions and put them in a freezer for days. You just have to learn some basic rules for storing prepped food. In all case, it's always better to eat things fresh, so I prefer cooking simpler meals most of the time and eat them the same day.
Learning to cook also removes the need to add meat to every meal. Meat always tastes good, and it takes less thinking to prepare than most vegetarian meals because we're not used to cook without it. It's quite incredible to see what you can do with beans and lentils though. One of my favorite vegetarian recipes is lentil carbonara. I love pasta. I also love lard, but coral lentils blend so well with sour cream and melted cheese that I prefer them.
I'm lucky to not be a picky eater. It's probably because I was raised to eat what was in front me, but I also think it's important to eat to live, rather than living to eat. Food porn is nice, but it can get in the way of accomplishing more important things.
