Cook the risoni pasta according to package instructions until al dente. Drain and set aside.
In a pot of boiling salted water, blanch the green beans for about 3-4 minutes until bright green and tender-crisp. Drain and immediately transfer to an ice bath to stop the cooking process. Drain again and set aside.
In a large skillet, heat 1 tablespoon of olive oil over medium heat. Add the halloumi slices and cook for about 2-3 minutes on each side until golden brown. Remove from skillet and set aside.
In a large bowl, combine the cooked risoni, blanched green beans, lemon juice, garlic powder, salt, and pepper. Toss to combine.
Gently fold in the parsley and cherry tomatoes.
Slice the golden halloumi and place it on top of the salad before serving. Drizzle with the remaining tablespoon of olive oil.
