     Ingredients for Chicken Fajita Bake: Chicken, Bell Peppers, Red Onion, oil, spices, and cheese
    I will admit it.  I do not really like meal planning.  No, I really don’t.  That’s why I started Hoppin Meal Plans, because I know I’m not the only one to feel this way.  Fortunately, as I sat down with my calendar to create my plan a few things help me.  Nothing helps more than Taco Tuesday!  Who came up with that anyway?  I owe them a thank you.  I do not do tacos every Tuesday, but my family does like Mexican so plugging a Mexican inspired dish in each week is a no-brainer. 
    This Fajita Bake is a simple and versatile way to get your Taco Tuesday fix.  It’s basically a sheet pan recipe in a baking dish.  Oh, this means I don’t have to wash a sheet pan after dinner, because I served dinner in the same dish I cooked it in.  So, let’s get started!
    Start by preheating the oven to 375.  Take your chicken breast and trim any fat off of them.  If the breast are large and thick, you will want to cut them in half so that they are thinner.  If the chicken breasts are too thick, they might not cook all the way through. 
    Chicken breast ,seasoned with Mexican seasoning, in a baking dish.
    Next, season your chicken breast.  The recipe calls for taco seasoning, but any sort of Mexican seasoning will do.  I was a little low on my taco seasoning mix, but I did not want to take the time to mix up another batch, so instead I used Penzey’s Southwest mix.  This mix includes some of those classic Mexican/Tex-Mex flavors like cumin, onion, and garlic, and gets a little kick from a variety of peppers, but the sweet ancho pepper keeps the flavor light. 
    Once you have selected your seasoning, sprinkle it on the chicken breast and place the breasts on the bottom of your baking dished. 
    Bell Peppers and Onion on top of the seasoned chicken.  Oil is then drizzled on vegetables.
    Next layer: vegetables.  I used three bell peppers and a red onion today, but mix it up.  Red onion too strong?  Flip it out for a sweet onion.  The bell peppers at the store this week were a little on the small side, so I went with three of them.  I didn’t mind this at all – it let me get some more color into my dish.  You will want to slice the peppers and onions thinly so they cook all the way through.  Plus, they’re easier to eat as a fajita if they are thinner!  Or, you could just but presliced peppers and onions in the produce section of the grocery store.  I am all for shortcuts! 
    Place your thinly sliced peppers and onions over the chicken breast.  Spread them out in an even layer.  Take your oil and drizzle it over the peppers. 
    Mexican cheese is added to the chicken and vegetables for the chicken fajita bake.
    Finally, sprinkle your cheese over the peppers and onions.  I used just a basic Mexican mix, but if you want a little more spice, especially if you’re using lighter flavored onions or taco seasoning, you can add the heat here by adding in a cheese like pepper jack.  The cheese is optional, so if you are avoiding dairy, just omit it.
    Place the dish in the oven and bake for 35-45 minutes.  Your chicken should be cooked through.  Remove from oven and serve with your favorite toppings and garnishes.  We always have salsa, sour cream and guacamole or fresh avocados on hand.
