Bring a large pot of salted water to a boil. Add the Jersey Royal potatoes and cook for 10-12 minutes, or until slightly tender. Drain well and set aside.
While the potatoes are cooking, prepare the sauce. In a small bowl, combine the black bean sauce and soy sauce. Set aside.
Heat the vegetable oil in a wok or large frying pan over medium-high heat. Add the garlic and ginger and stir-fry for about 30 seconds, or until fragrant.
Add the green beans to the wok and stir-fry for 3-4 minutes, or until they are bright green and slightly tender-crisp.
Add the cooked Jersey Royal potatoes to the wok and stir-fry for another 3-4 minutes, or until they are heated through and slightly browned.
Pour the black bean sauce mixture over the potatoes and green beans. Stir-fry for 1-2 minutes, ensuring everything is coated evenly.
Add the cornstarch slurry to the wok and stir-fry for another minute, or until the sauce has thickened slightly.
Remove from heat and stir in the sesame oil.
Garnish with sliced spring onions and toasted sesame seeds, if desired.
Serve immediately.
