01 - Divide the shredded cheeses equally among three separate mixing bowls. Incorporate the spirulina powder into the first bowl, the beet powder into the second, and the turmeric powder into the third. Stir each batch thoroughly until the cheese exhibits an even, vibrant color.
02 - For an improved texture and melt, optionally lightly mix a small amount of cream cheese into each of the colored cheese mixtures. This helps the cheese adhere together for smoother melting.
03 - Arrange the four slices of bread on a clean surface. Lightly spread a thin layer of softened butter onto one side of each slice.
04 - On the unbuttered side of two bread slices, artfully arrange portions of the differently colored cheeses in a random, patchy, or striped pattern to achieve a 'chaos' aesthetic. If using, sprinkle the chopped spinach evenly over the cheese.
05 - Place the remaining two bread slices on top of the cheese-laden slices, ensuring the buttered sides are facing outwards.
06 - Heat a nonstick skillet or griddle over a medium heat setting. Carefully place the assembled sandwiches onto the preheated cooking surface.
07 - Cook each sandwich for approximately 3 to 4 minutes per side. Apply gentle pressure with a spatula to promote even browning and ensure the cheese is thoroughly melted and gooey. Continue until both sides are golden brown.
08 - Remove the grilled sandwiches from the skillet. Allow them to cool for a moment before cutting them in half to reveal the striking interior colors. Serve immediately while hot.
