I hope your dad is able to transition into healthier eating. I like Kaizen as a healthier alternative to regular pasta.
When I make Mexican rice I make the rice half regular rice half cauliflower rice and no one in my house has ever complained.
For “fried” chicken that is not fried i like this recipe, I make it all the time with legs and thighs I change the seasonings to garlic and onion powder and no pepper flakes and a bit of parsley and is always good:

I have never heard of that before, thank you for that suggestion!! He loooooves pasta, and I’ll have to look into that flour alternative that it’s made with. Thank you, Mayra!
