I think granola is one of those neither good or bad things. Like, it doesn't have a ton of nutritional value, but it's not horrible for you either. The biggest issue with it is the store bought varieties can have a lot of added sugar. That being said, I use 1/3 of a cup (half a serving) of a store-bought granola in my breakfast with yogurt, apples, and cinnamon. It just adds a nice flavor and texture that I like and it makes my breakfast more enjoyable.
Peanut butter is not bad at all, but you have to watch your amounts. 2 tbsp of it is almost 200 calories... so not a lot of bang for your buck. But it does have some protein in it that can help fill you up. Same thing for nuts... high in calorie but does have some good nutritional value. I reserve them for when I'm out and about and can't eat a normal meal.
As for the Special K items... I avoid them. If you really look at them they don't provide a lot of nutrition, even though they tout "high protein".
I can't think of any cereal that is all that filling. I feel like most cereals (not counting hot ones like oatmeal) are empty calories. I use them more when I just want a sweet treat... not as a meal. You can try doing oatmeal and add in things like fruit and a bit of peanut butter and see if that keeps you full.
