Ham and Potato Soup

Peel and dice up potatoes. Put them in a pot along with water, celery, onion, ham, and carrots. Bring to a boil. Once they come to a boil, lower heat and simmer until potatoes are softened. Stir in bouillon cubes, salt, and pepper. In another pan, melt butter over low heat. Add in flour and whisk until combined. After about a minute, stir in milk and minced garlic. Cook and stir this until thickened. Once this mixture is thick, pour into pot with potato mixture. Stir all together. Serve with cheddar cheese and green onions on top.
