Chicken and Vegetable Quinoa Casserole

Okay, it’s confession time. This is kind of a serious one, but I feel like it needs to be out there.

You ready for this?

Despite having a blog with the word “greens” in its name, I have been really (like REALLY!) bad at eating my vegetables lately. I could blame it on the baby, but it really comes down to falling out of the habit of meal prepping.

Before baby, I was a champion meal planner, making my lunches for the week on Sunday, making sure I had something quick to eat before work every morning, and usually having a game plan for dinner. Since having Lars, I’ve gotten lazy. Breakfast is usually granola and yogurt or oatmeal, lunch is usually eaten with one hand standing in the kitchen (i.e. hummus and crackers), and by the time dinner rolls around I have a big fat zero in my veggie count for the day. And then we order pizza for dinner.

Big fail! Now that I’m headed back to work, I’m determined to become that stellar meal planner I once was and start putting the “greens” back into greens & chocolate!

This Tomato Basil Chicken and Vegetable Quinoa Bake was the perfect meal to get me started in the right direction. Not only is it packed with veggies (zucchini, summer squash, bell peppers, and onion) but the sauce base is  Traditional Italian Sauce from Prego®which actually provides 40% of your daily recommended value of vegetables. In every serving. Um, yes please!

Another great thing about this casserole is that when you prep the veggies, quinoa, and chicken in advance, it comes together in the blink of an eye, making it a perfect weeknight meal. Without a doubt, this will definitely become a go-to meal for us. It’s healthy, filling, and also makes great leftovers!
