@solarsupermama. You had me giggle with your MIL!
I will say, because of my daughter's allergies we have had to completely create a dish that wasn't offered on the menu. Like maybe their GF bread has sunflower seeds so she can't have that, and their fries are coated in flour, so we order a plain burger Patty, then add white rice and steamed broccoli. With her restrictions we don't do fast food though. 😉
Well, allergies are a whole different thing. You have to do that to keep her healthy. My MIL is just ridiculous. Don't let me get started.
