Place pork roast in slow cooker with 1/2 cup of water (or you can spray slow cooker with cooking spray). Season with salt, cracked pepper and garlic powder. Cook on low for 8-10 hours.
Scrub and cut red potatoes into quarters. Boil for about 10 minutes, until soft and "mashable." Drain water and place in bowl to mash.
Mash cooked red potatoes with potato masher. Add sour cream and milk (I'm all out of butter, but 2-3 Tbsp butter would be good too!). Add more milk for creamier potatoes or less milk for chunkier potatoes. Add crushed garlic. Season with salt and pepper to taste.
Cook frozen veggies according to package instructions.
Remove pork from slow cooker when it's finished. Slice into 1/3-1/2 inch slices.
Serve Slow Cooker Pork Roast with side of mashed red potatoes and green beans.
