Add Food Coloring: Take each bowl of cheese and add a few drops of food coloring. Stir them well until the cheese is vibrantly colored. The colors should be bright and inviting, setting the stage for your masterpiece.
Assemble the Sandwich: Butter one side of two slices of sourdough bread. Place one slice butter-side down into a heated skillet. Layer the colored cheese in a fun design on top, showcasing all those beautiful hues, then cover it with the second slice, butter-side up.
Cook the Sandwich: Grill your sandwich for about 3-4 minutes on medium heat, keeping an eye on it until the bottom is golden brown. Flip it gently and cook the other side until it’s golden and the cheese is melty and gooey.

Rainbow Grilled Cheese Recipe FAQs
How do I choose ripe ingredients for the Rainbow Grilled Cheese?

How should I store leftover Rainbow Grilled Cheese?
You can store any uneaten sandwiches in an airtight container in the refrigerator for up to 1 day. Wrap each sandwich tightly to prevent it from drying out. This way, you can enjoy your colorful creation on a busy day!

What should I do if my cheese isn't melting properly?
Very frequently, this happens if the heat is too high or the cheese isn’t shredded finely.

If needed, cover the skillet with a lid to trap steam, helping the cheese melt thoroughly.
Are there any dietary considerations with the ingredients?
