01Heat a grill over medium heat and lightly oil the grates.
02Using a vegetable peeler or spiralizer, cut the summer squash into ribbons. They will look like the wide pasta noodle known as pappardelle.
03In a bowl, add squash ribbons, salt, pepper, oil, and lemon juice and mix well.
04Divide pizza dough into 4 equal pieces. Using a rolling pan or your hands, gently stretch each piece of dough into a personal size pizza, approximately 8 to 10 inches in diameter, and place on an oiled baking sheet. Note: perfect circles of dough not necessary!
05Place each small dough round onto the grill and cook for 2 minutes. Flip and cook an additional 1 minute then remove from grill and place back on baking sheet.
06Top each pizza with one-quarter of the squash mixture. Top each pizza with 3 to 4 dollops of ricotta cheese. Sprinkle each pizza with 1 tablespoon of grated parmesan.
07Return the pizzas to the grill and close the cover. Cook until toppings are warmed through, crust is crispy, and cheese is golden brown to your liking, approximately 5 to 8 minutes. Remove from grill and garnish with red pepper flakes, pistachios, and/or basil.
