Sure. But, if you lack the ability to make good use of frozen produce, then that maybe isn't a realistic option, anyway. Then you might be looking at something more like a choice between TV dinner and McDonald's.
I found quiet revelaing that a Dollar store in a pre announced shoot with a TV station couldn't show any more produce than is to be seen in this shot https://youtu.be/GtAvJBAJfnE?t=389
I specifically chose the phrase "make good use of" over the word "cook" because it's an important distinction.
Nobody can make a decent meal exclusively out of frozen vegetables; there just aren't enough macronutrients there. And everyone wants their meals to be appetizing. So it's not just about whether or not you can make frozen vegetables hot, it's about whether or not you can feasibly incorporate them into a nutritionally complete and appetizing meal.
Also, with TV dinners, you can buy just tonight's dinner on the way home from work, heat it up as soon as you get home, and have nothing left over to store. So, even though the food is frozen, there's no need to own a working freezer. With frozen vegetables, unless your meal plans typically involve eating half a pound of Normandy blend in one sitting, not so much.
Also, if you're time poor, you may not have time to actually cook or meal prep. Working multiple low income jobs is not uncommon, and those jobs often tend to have very erratic schedules that you can't plan around. (Usually around limiting your hours below 30, so that the health insurance requirement does not kick in.)
