1. Peel the potatoes and cut them into bite-size pieces.
2. Grab a large pan and place the cut potato chunks in it.
3. Barely cover the potatoes with some water. Please note, at this point, you can pressure cook the potatoes with one cup of water (depending on your pressure cooker). I pressure cooked them on high for 6 minutes, and did a quick release. Then continue on with the recipe.
4. Add the butter and bouillon.
5. Add garlic salt.
6. Add the canned milk, and stir.
7. Bring to a boil, cover, and turn the heat to medium.
8. Continually watch for the potatoes to be tender. Replace the cover after stirring them.
9. When done, mash a few of the potatoes to thicken the soup.
10. Add salt and pepper to taste.
