Frequently Asked Questions

Do I Have To Use Frozen Peppers And Onions?

To save some time prepping this recipe we opted to use a 20 ounce bag of frozen pre-chopped peppers and onions. However you can use and cut up your own fresh bell peppers (any color will work… red, yellow, orange, even purple!) and onion. You will want end up with about 2 cups chopped bell pepper and 1 cup onion. There is no difference in the cooking time using fresh bell peppers and onions over using frozen.

Can I Use Other Cuts Of Meat In This Casserole?

This recipe would be great using boneless skinless chicken thighs as well instead of the chicken breasts. However thigh meat does not shred quite as easily as breast meat does. In that case instead of shredding I recommend dicing the cooked chicken thigh meat up once it is done cooking,

Can I Use Make My Own Homemade Fajita Seasoning?

If you cannot find packets of fajita seasoning at your local grocery store or you just want to make your own fajita seasoning mix without any added salt, sugar, MSG or anything else unhealthy… check out our Homemade Fajita Seasoning Mix.
