Roasted Pumpkin Salsa

Preheat the oven to 350 degrees F (175 degrees C). Line a baking sheet with parchment paper.

Combine pumpkin, onion, oil, and cinnamon in a plastic bag; coat well. Spread mixture onto the prepared baking sheet.

Bake in the preheated oven until lightly browned, about 25 minutes. Remove from the oven and let cool completely, 15 to 30 minutes.

Combine tomatoes with their juice, cilantro, jalapeno, ginger, and grapefruit juice in a medium bowl. Add roasted vegetable mixture and mix well. Chill in a refrigerator for 1 hour to combine flavors.
