Heat oil over medium-high heat. Add 1 diced onion and garlic; cook until soft, about 8 min. Add tomatoes, red pepper, ginger, cinnamon and kosher salt; simmer, stirring occasionally, until mixture thickens, 20 to 25 min (less time if using canned tomatoes). Remove from heat and cool. Serve on grilled or toasted slices of French bread spread with ricotta and a drizzle of honey. Chutney keeps chilled for up to 5 days.
Notes
Can use canned tomatoes - simply reduce the cooking time.
