I hesitate describing anything as "grown up" but since I used sriracha in the 'recipe', I deemed it appropriate. Grilled cheese is possibly my favorite type of sandwich; what's not to love about melted cheese paired with crusty bread that's grilled with sizzling butter? I love to add avocado for a little more texture and lightly swipe on some mayo combined with a dollop of sriracha My tip for making a grilled cheese even better: use butter both in the pan AND on the bread and cover the grilled cheese while it cooks--it really melts the cheese.
What do you use to spice up your grilled cheese? I'm always looking for new additions!
