In a large shallow pot, sauté the onion in about one tablespoon olive oil over a medium–high heat, until just softening. Set aside and wipe down the pot.

Add another tablespoon oil to the pot and the defrosted cubes of garlic and ginger. Swish the garlic and ginger around with a wooden spoon and add the honey and sugar snap peas. Toss them vigorously so that they cook evenly, for only a few minutes, so that their color brightens but they’re still crunchy. Remove from heat.

Pour the snap peas into your serving dish. Toss in the red onions and diced mango, and sprinkle lightly with sesame seeds. Serve at room temperature.
