Peel and core 5-6 medium apples. Slice each apple into 6-8 slices and then cut each slice into thirds. The exact size doesn't matter as much as keeping your chunks even in size.
Add the apple chunks to a large pot. Add in ⅓ cup brown sugar, 3 Tbsp water, 2 Tbsp butter, and 1 Tbsp cinnamon. Stir with a spatula to coat the apples evenly.
Cover with a lid, and cook over medium high heat for 5 minutes or until apples are just barely starting to become tender.
In a small bowl, add 1 Tbsp cornstarch and 3 Tbsp water, and mix together to form a slurry.
Turn the heat down to medium-low. Add the slurry, 1 Tbsp lemon juice, and ¼ tsp salt to the apple mixture and mix thoroughly.
Cover with the lid and let cook another 13-18 minutes stirring occasionally until apples are fork tender and gooey. If the mixture ever gets too dry, add another 1-3 Tbsp of water.
Once apples are to desired firmness, remove from heat. Add ½ cup of the pecans roasted above, stir, and set aside.
