Preheat oven to 425°F / 220°C.
In a small bowl, mix together the Sucanat, Chinese five spice powder, chili powder, cayenne, sea salt, and pepper.
Spread the pecans on a baking sheet and toast for 5 minutes until fragrant.
Remove the hot pecans from the oven and immediately add them to the bowl with the spice mixture.
Toss to combine, then scrape them back onto the baking sheet.
Return the pecans to the oven to melt the spices and sugar onto the nuts, about 2 to 3 minutes more.
Remove and set aside to cool.
Place the pear slices in a single layer on a baking sheet and roast until lightly browned around the edges, 5 to 8 minutes.
While the pears roast, whisk together the white balsamic vinegar, olive oil, and crumbled blue cheese in a small bowl to create the dressing.
In a large salad bowl, combine the baby spinach and the warm roasted pears.
Pour the dressing over the top and toss gently to coat.
Divide the salad among four plates and top with the spiced pecans before serving.
