I'm not saying that I was lazy, but when you rely on instant cooking or fast food for most of your meals for such a long time, it's habit forming. Further, when your working life and commute home consume so much energy, it's hard to walk into the kitchen at night and start cooking and chopping veggies. Even though it takes minimal effort, it may not be the most fun thing to do after a long day.
You can overcome this once you start to enjoy the food you make and once you get used to and familiar with the vegetables. With a bit of practice and discipline, I realized that it didn't take that much time and it was very simple. Peeling carrots, potatoes, yams, and beets can be done each in 30 seconds and chopping them up takes just another 30 seconds. After that, you throw them into a pot with water or a skillet with some olive oil and you're cooking. When you get used to chopping veggies for salads like cabbage, tomatoes, cucumbers, and radishes, it goes so quick, you forget you are cooking.
With some discipline, I reduced the effort further by making larger batches of food, especially soups, so that I could store it in the fridge, heat it up in minutes after getting home, and start eating in less than 10 minutes. That is eating instantly and nutritiously at the same time!
Part of the process of enjoying to cook is getting to know the vegetables you use and what chopping techniques suit the meals and your taste. You start to become and expert and you also learn to pick out good veggies and fruit from the store which makes cooking even better.
In fact, after a while, once I started getting good at cooking with certain veggies, I actually wanted to explore new ones to see what they were like and how they handled in recipes and tasted in the end. So to some extent, it becomes a hobby, and it gave me new things to think about that benefited my experiences in the kitchen and health. So don't worry too much about having to chop veggies. It will lead to good cooking and good times! This article shares some similar experiences.
