Some things yes, most no. I cook a much wider variety of foods than my mom did, and I don't keep quite as tight a handle on the grocery budget. But I also don't cook many meals as time-consuming as those my grandmother - who was basically my SAH parent until her health started to fade - made either.
My mom was a very 1970s-American cook - meatloaf Monday, taco Tuesday, shake-n-bake and canned corn, casseroles prepped on weekends to heat during the week, etc. Not bad food and not terribly unhealthy, other than perhaps the sodium content, but not very creative or varied either. Ethnic food, in my household, was tacos or lasagna. That was made much worse by the fact that my brother was VERY picky when we were growing up, so changing up routines was a whole can of worms that I totally understand (now, as an adult/mom... not so much back then) her not having the energy to open after working all day.
My cooking style is more improvisational. I use a lot less canned stuff but a lot more fresh or frozen veggies. There are a couple of more involved recipes that I have in the regular rotation - shepherd's pie, cordon bleu casserole, paella - but for everyday cooking I do a lot of grilled or slow-cooker mains with frozen veggie sides, and there are only a couple of the things I grew up eating that ever make it onto the menu. The kids do love shake-n-bake pork chops so I do that from time to time, and we do taco night once or twice a month, usually when we have extra kids staying the night. I also serve a lot of things that my mother would think of as side dishes as mains, especially if they contain some meat - for example, in my book well-prepared collard greens with cornbread is a meal in itself, and a bit of grilled chicken is enough to make a salad into an entree.
