While your skillet heats over medium heat, toast the walnuts for 3-4 minutes, shaking the pan occasionally, until fragrant and slightly darker—this deepens their flavor and ensures maximum crunch in the finished salad. Meanwhile, mince the garlic clove very finely. Once the walnuts are toasted and cooled slightly, whisk together the minced garlic, cider vinegar, honey, mustard, salt, and black pepper in a small bowl to combine the flavors, then slowly drizzle in the olive oil while whisking constantly to emulsify the vinaigrette.

Slice the apples into 1/4-inch thick wedges and toss them immediately with the fresh lemon juice—this prevents browning and adds brightness to the dish. Thinly slice the red onion into half-moons. Crumble the goat cheese into bite-sized pieces, separating about half to use for topping later. I like to keep the goat cheese cold until the very last moment so it maintains its creamy texture and doesn't melt into the salad prematurely.

Place the fresh spinach in a large bowl, then add the lemon-dressed apples, sliced red onion, toasted walnuts from Step 1, dried cranberries, and half of the prepared goat cheese. Pour the vinaigrette from Step 1 over the salad and toss gently but thoroughly, ensuring every leaf is coated with dressing while keeping the apples intact. The gentle tossing is important—you want to distribute the dressing evenly without bruising the delicate spinach leaves.

Divide the dressed salad among serving plates or transfer to a serving platter. Top each serving with the remaining crumbled goat cheese, allowing it to rest on the warm salad where it will soften slightly and become creamy without fully melting.
