In a small saucepan over medium heat, add pear slices, 1 Tbsp. of honey, half of the orange juice, cinnamon, ginger, and a pinch of salt.
Stirring occasionally, cook until the pears are slightly soft but still have a crunch, approximately 4-6 minutes.
Remove from heat and let cool.
In a medium saucepan over medium-high heat, bring 2 cups of water, remaining half of orange juice, and ¼ tsp. salt to boil.
Add grits to boiling water and turn down to medium-low heat.
Cook grits for 14-16 minutes, stirring occasionally until grits are creamy with a small amount of bite.
Remove from heat and stir in remaining tablespoon of honey.
Spoon grits into a bowl and arrange cooked pears on top.
Drizzle remaining syrup from pears on grits and top with walnuts (optional).
