Frozen Veggie Meals

When I went vegetarian, I sort of pictured the meals I'd be eating to be an array of different veggies, beans/tofu for protein, and for the most part pretty natural. And I imagined making my food myself so my mom wouldn't have to deal with it and all would be right in the kitchen.

Fast foward to now, my mom insists on still cooking a seperate meal for me, and most of the time it consists of a frozen, veggie tv dinner type thing. I understand that this is quick and easy for her, but I'm a little tired of eating these processed meals every night, every day of the week. I've offered countless time to prepare my own food on the occasion (though i'd happily do it every night), but she insists she's fine doing it. She's not though, because I've heard her complain about having to make two sets of meals every night. does anyone else have a problem like this? if so, how can i convince my mom that letting me make my own food would save both of us a lot of trouble?
