This looks wonderful! I haven’t cooked with quinoa, but I love the idea of adding it to granola!

I eat quinoa for breakfast with berries. Maybe they would like that. I use milk too. But your dish looks yummy and gooey good.

Thanks Julie for your visit
That looks really good – I love quinoa
Thank you Sue!
Quinoa seems to be popping up everywhere these days! This looks like a particularly tasty way to eat it.
Quinoa is such a healthy addition when going meatless due to its protein content! This looks yummy… Keep offering it to your kids, they’ll come around. My 4 adult sons all cook, and have almost no dislikes, but I kept offering things to them when they were little… Go Ilona!
Thank you so much Tamara for your suggestions. I think I should stick with offering:)
This looks fabulous! We love mexican food in our house and I can’t wait to try this 🙂
Thank you Lauren!

Yumm!! This is so mouth-watering, bookmarking this recipe!!
Thank you so much Sam!
I made this for dinner tonight and it was a hit!
I am so happy to hear that!
I cooked this for my husband tonight, who is a professional chef. He was very skeptical of this being good since he is such a huge meat eater, and this is vegetarian. But he absolutely loved it!! He even went back for thirds! It’s a healthy, comforting, flavorful and easy dish that we will be putting into the regular rotation 🙂 I think one of the keys too is that we invested in some really good taco sauce found at Whole Foods that included red pepper and cumin. Thanks for sharing the recipe!
Thank you so much! I am so happy to hear the good news. I agree if you invest in really good taco sauce that you like you’ll love the whole dish:) Thank you for trying my recipe.
Loving this when the corn or flour tortillas are not jiving with my body:)
Thank you Jennifer!
