Mix together peanut butter, tamari (or soy sauce), sesame oil, rice vinegar until smooth. You will need to add warm water to the sauce to thin, one teaspoon at a time until you reach desired consistency. Feel free to add 1 TBSP honey for a bit of a sweeter touch to the peanut sauce (this is more traditional, I chose to leave the honey out). Pour over broccoli and enjoy warm or chilled. Also note that the sauce can absolutely be to taste - if you want to add a bit more soy sauce or vinegar, do so! Enjoy!
