Busy schedule, quick meals

I have just recently started working 2 jobs. One full-time during the week,and my part-time on the weekends. And I pick up a few hours during the week after my full time gig. I really do enjoy cooking but at the moment,I literally have no time to meal prep like I normally do. I am looking for some easy frozen meals that I can make into meall prep meals to Eliminate the cooking process. What are yalls to go to frozen meats, veggies ,snack ,Breakfast foods or whatever you eat. I've never really eaten frozen foods. I usually cook my food so I don't know what's good and what's not good.
