Method
- Preheat your oven to 400°F (200°C). Using a sharp paring knife, carefully cut the tops off the pumpkins or acorn squash, then scoop out the seeds and pulp, leaving a clean shell.

- Brush the insides of each pumpkin or squash with olive oil, sprinkle with salt, and place them on a baking sheet. Roast in the oven for about 20 minutes, until the flesh is tender and caramelized around the edges.

- While the pumpkins roast, finely chop the onion and cook in a skillet with a tablespoon of olive oil over medium heat until golden and caramelized, about 10-15 minutes. Set aside.

- In a mixing bowl, combine the ground beef, Worcestershire sauce, salt, pepper, and half of the caramelized onions. Gently mix until just combined, then form into four equal-sized patties, about 2 cm thick.

- Heat a skillet or grill pan over medium-high heat. Cook the burger patties for about 4-5 minutes per side, until they develop a nice crust and reach an internal temperature of 160°F (70°C). Place cheese slices on top during the last minute of cooking to melt.

- Remove the roasted pumpkin halves from the oven and let them cool slightly. Carefully fill each with a burger patty, then top with remaining caramelized onions and cranberries if desired.

- Drizzle each burger with spicy mayo or mustard, then cap with the pumpkin lid. Serve immediately while warm, allowing the flavors to meld and the pumpkin to serve as a flavorful edible plate.

Notes
Ensure pumpkin shells are stable on the plate before filling. Check pumpkin tenderness with a skewer before removing from oven. Add cheese in the last minute of cooking to prevent burning.
