Toss together the rolled oats, rice cereal, and chocolate chips in a large bowl with a pinch of salt. Set aside. Add peanut butter into a microwave safe bowl. Microwave for 30 seconds and stir. Repeat until the peanut butter is melted. Add in the honey and vanilla. Stir thoroughly to combine. Pour the mixture over the cereal and oats mix. Stir until incorporated. Pour the mixture into a casserole dish lined with wax paper. Press down to form an even layer. Let set in the fridge for 1-2 hours. Cut into bars and enjoy.
