I do a lot of meal prep and freeze food. Things I make regularly include lasagna, meatballs, homemade chicken tenders, enchiladas, chicken pot pies, and casseroles.
I have also precooked and portioned pulled pork, ground meat for Mexican food, and chicken.
I have precut veggies and froze them for dinner kits and have cleaned chicken and froze it in the marinade so I just have to defrost and add to the dinner kit or grill.
