For the lemon-honey vinaigrette: Combine the oil, honey and lemon juice in a small jar, and shake well to combine. Add salt and pepper to taste, and set aside.
For the salad: Put the arugula on a salad plate and top with the cooked sorghum. Top with peach slices and sprinkle with Marcona almonds. Drizzle 2 tablespoons Lemon-Honey Vinaigrette on top, or to taste. Serve immediately.
The sorghum can be cooked a day or more ahead of time and lightly warmed in the microwave before you prepare the salad. If you can't find whole-grain sorghum, feel free to use cooked quinoa or your favorite cooked whole grain.
