- 1 extra large crown of broccoli finely chopped in a food processor (see note)
- 2 large eggs
- 1/2 cup shredded mozzarella cheese
- 2 thick slices cheddar cheese
Cut broccoli into small florets and place into food processor. Pulse until all of the broccoli become crumb-sized.
Measure out 3 lightly packed cups of broccoli and place into a large, microwave safe mixing bowl. Cover surface of the bowl with plastic wrap. Place bowl in the microwave and heat at full power for about 1 minute to 1 1/2 minutes. Broccoli should be soft and cooked.
Let broccoli cool slightly until it's no longer too hot to touch. Divide broccoli into three batches. Take your first batch and place in between several paper towels or into a cheese cloth or tea towel. Wring cloth a few times, draining out most of the water from broccoli. You do not need to squeeze the broccoli completely dry, but you do want to remove most of the water. Place dried broccoli back into mixing bowl and repeat with remaining two batches of broccoli. You should be left with 1 1/3 cup of dried broccoli when you're done squeezing out the water.
Add eggs and cheese to the broccoli. Stir until everything is completely combined, resembling a broccoli paste.
Line a large baking sheet with parchment paper. Preheat oven to 400°F. Take 1/4 of your broccoli mixture and place onto the baking sheet. Spread and shape the broccoli mixture to resemble a square that is approximately 4 1/2 inches wide and 1/8 inch thick. Repeat with remaining broccoli mixture, spacing each square 2 inches apart. You will have a total of four squares which will be the bread slices for your sandwiches.
Bake for about 15 minutes until edges are golden and the breads feel firm to the touch. You should also be easily able to slide the breads off the parchment paper.
Form sandwiches with your breads by placing a slice of cheese in between two slices of bread. The softer side of the bread (that was facing down in the baking pan) should be the inner sides of your sandwich, with the slightly crispy sides facing out. Add some oil to a cast iron skillet over medium heat. Once skillet is hot, place your sandwiches into the pan. Use a small lid that just covers the sandwiches to weigh down the sandwiches and help retain in the heat. Cook until bottom of sandwiches are browned and crispy and then flip over and repeat until cheese is completely melted and both top and bottom of sandwiches are browned and crispy.
You'll need three cups (lightly packed) of finely chopped broccoli which is approximately one extra-large broccoli crown or two small ones.
