Easy Chicken Enchilada Casserole

Easy Chicken Enchilada Casserole is a fun cross between enchiladas and fajitas but without all the work. Using a rotisserie chicken for this is a time-saving shortcut that I love taking advantage of.

If you don’t have a rotisserie chicken laying around, regular cooked chicken breasts will do. If you have an instant pot, you could use this quick recipe for instant pot chicken breasts to have the chicken done in a flash.

When I try to get my kids to eat vegetables, I usually get a whole lot of this.

Veggies Post-1

They are not big fans. It usually ends up being a matter of bribing them with a treat after dinner, or withholding their favorite part of the meal until they’ve eaten “enough” of the healthy part. I’m not a fan of either of those methods.

I’m making a wider variety of vegetables available for my kids to eat…if they choose. I’m encouraging instead of bribing, and trying to incorporate more vegetables in our normal rotation.

As a busy mom of 7, I’ve learned a few things over the years about kids and which battles to pick, and the whole “vegetable war” is 100% not worth it.
