Line an 8" square pan with parchment. Preheat oven to 350 degrees.
In a large bowl, place the oats and the crispy rice cereal, and any other additions you desire; dried fruit, coconut, mini chocolate chips?
In a small saucepan over medium heat, place the peanut butter, half of the jam, the water and the salt. Stir and let heat until everything is melted all together.
Remove from the heat and pour over the oat/crispy rice mixture in the bowl and mix well together.
Press the mixture into the prepared pan. Now dollop additional blobs of peanut butter and the reserved jam over the top of the bars, and use a knife to swirl it.
Bake in preheated oven for about 20-25 minutes. Remove and allow to cool before cutting into bars. Store in an airtight container on the countertop or freeze them if you are making a bigger batch.
