We all know that Tex-Mex food is high on my list so it’s not a big surprise to find the poblano and cumin on the ingredients list!
Being a food writer is lots of fun but it’s also tough because you are constantly looking ahead and trying to figure out what everyone is going to want to eat two months from now. Anyway, I came across a recipe for ranch chicken bubble-up on the Pillsbury site. It was made with biscuit dough and chicken and lots of my favorite flavors. And it was loaded, loaded, loaded with carbs. I thought the flavors would be great, though and decided to use cauliflower as the foundation. It worked perfectly!
Once you cover the chicken breast with the southwestern seasoning you’ll need to let it sit for 10 minutes or so while you are steaming the cauliflower and grating the cheese — or playing SimCity BuildIt. Whatever.

During that time the meat absorbs some of the flavor from the seasoning and it just tastes better. You’ll need a cast iron pan so that you can get it super hot. That’s how you are going to get that gorgeous caramelization on the chicken. Once everything is mixed together you just slide it under the broiler for a few minutes so the cheese can get bubbly and you’ve got an amazing Tex-Mex dinner with just a little over 3 carbs per serving.
Here’s that ranch chicken casserole recipe!
