Why Use RO*TEL® Diced Tomatoes & Green Chiles?

Please note that this post is NOT sponsored by RO*TEL®. I just used their canned diced tomatoes and green chiles in this recipe because they make this casserole a zillion times easier to get on the table. They’re full of flavor, and they make throwing this casserole together incredibly easy.

I typically pick them up at Walmart, but you can also find them at Target and most grocers in the U.S. If you can’t find them or are located outside of the U.S., you can use 12 oz diced tomatoes and add additional seasoning to the casserole to taste.

You can also get them on Amazon:
