Butter and sugar sandwiches. That cannot be good for you, which is how you know it's amazing. I'm a big fan of any sandwich that uses copious amounts of butter. Grilled cheese is my main sandwich because of that. Slather on the butter like it's a condiment. I figure since we put butter in pastries and on pancakes, it's gotta be good with sugar on plain bread. That's just simple science.
This reminds me of a dessert my mom used to make. It was tortillas with butter, sugar, and cinnamon. Basically this exact same concept except with cinnamon. You know why we wouldn't have them sometimes? My mom would say we were out of cinnamon. I'm such an idiot. I should have told her to make it with just the sugar and we'd be fine!
