01 - Preheat a grill or grill pan over medium-high heat.
02 - Brush the apricot halves lightly with olive oil. Place them cut-side down on the grill and cook for 2–3 minutes, until grill marks appear and the fruit is slightly softened. Remove and set aside.
03 - In a small skillet over medium heat, melt the butter. Add chopped almonds, brown sugar, and a pinch of salt. Toast, stirring frequently, until the almonds are golden and fragrant, about 3–4 minutes. Transfer to a plate to cool.
04 - In a small bowl, whisk together olive oil, balsamic vinegar, honey, Dijon mustard, salt, and pepper to make the dressing.
05 - In a large salad bowl, combine arugula and sliced red onion. Drizzle with half of the dressing and toss gently to coat.
06 - Arrange the grilled apricots and crumbled goat cheese on top of the greens. Drizzle with remaining dressing.
07 - Sprinkle the almond crumble over the salad just before serving.
