Trim the ends of the green beans and cut them in half. Cut the leeks into thin strips, cut the cherry tomatoes in half lengthwise. Cut the garlic into thin slices.
Add a drop of vegetable oil to a heated thick-bottomed frying pan and add onions, garlic and beans. Fry, stirring vigorously, for 1-2 minutes. Then add the butter and all the corn, continuing to vigorously stir.
When the corn is golden, drizzle the wine over the succotash and let it evaporate almost completely.
Add sweet chili sauce and cream, bring to a boil and remove from heat. Place in a bowl and garnish with basil sprouts.
