This is one of my fall favorites.
6 medium sized apples, peeled and sliced
1/4 cup sugar
1/2 teaspoon cinnamon
1/8 teaspoon sea salt or kosher salt
1 cup oatmeal
1 cup brown sugar
½ cup butter, melted
½ teaspoon sea salt or kosher salt
Combine apples, sugar, cinnamon, and salt. Place in a buttered 8x8 Pyrex dish.
Mix the oatmeal, brown sugar, melted butter and sea salt. Sprinkle on top of the apple mixture. Bake 40 minutes in 375 degree oven.
