Slice the tops off each bell pepper and set aside. Use a small carving tool or paring knife to carefully cut out friendly Jack-o'-Lantern faces on the front of each pepper. Set the carved peppers aside.
Preheat your oven to 375°F (190°C). Brush the outside of each carved pepper with a little olive oil and place them in a baking dish.
In a mixing bowl, combine the cooked rice, shredded cheese, chopped herbs, and a pinch of salt and pepper. Mix until well blended and the cheese begins to melt slightly.
Stuff each carved pepper generously with the rice mixture, pressing gently to fill all the nooks and crannies.
Place the top of each pepper back on and bake in the preheated oven for about 30 minutes, or until the peppers are tender and the cheese is bubbly and golden around the edges.
Remove from the oven, let cool slightly, then serve these playful, cheesy pumpkins while still warm and gooey inside.
