Prepare the vinaigrette by combining the canola oil, olive oil, seasoned rice vinegar, red wine vinegar, minced garlic, and a pinch of sugar together. Season with sea salt and freshly cracked pepper, to taste; whisk until well combined. Set aside to allow flavors to mingle.
Prepare the salad by combining the spinach, onion slices, dried cranberries, and toasted pepitas together in a bowl.
Whisk the vinaigrette well then drizzle some on the salad, to taste. Toss to coat evenly. Pour salad into the serving bowl then top with freshly cracked black pepper, to taste, apple slices, and goat cheese crumbles.
Serve immediately with additional vinaigrette on the side. Enjoy.
