I'm not sure if you're the person recommending to make your own frozen burritos, or just suggesting to make your own fresh every time...
Cooking includes making sure you have the ingredients at hand, and if you want something with meat and beans, it's not that fast. Plus, you still have to do dishes.
A frozen burrito can be thrown into a paper towel and walked out with in three minutes.
I'm not saying that everyone should microwave every meal, but people don't have the time, skill, or ingredients to make everything fresh, or meal prep.
