Bring a pot of salted water to a boil and cook the risoni according to package instructions. Make sure not to overcook it, as it should stay slightly firm. Drain and let it cool slightly before using.
Blanch the green beans in boiling water for a few minutes until tender but still crisp. Immediately transfer them to cold water to keep their vibrant color. Drain and set aside for later use.
Heat a frying pan with a little olive oil over medium heat. Add the halloumi slices and cook until golden brown on both sides. Remove from heat and let them rest slightly before cutting into pieces.
In a small bowl, whisk together olive oil, lemon juice, lemon zest, and garlic. Add salt and pepper to taste and mix until well combined. This dressing ties all the flavors together.
In a large bowl, combine the cooked risoni, green beans, and herbs. Pour over the dressing and gently toss everything together. Make sure the pasta absorbs the dressing evenly.
Top the salad with the golden halloumi pieces just before serving. Add any optional toppings like nuts or seeds for extra texture. Serve warm or at room temperature for best flavor.
