In the bowl of a food processor, combine the tahini and lemon juice and process for 1 minute, scrape the sides and bottom of the bowl then process for 30 seconds more.
Add the olive oil, minced garlic, cumin, and salt to the whipped tahini. Process for 30 seconds, scrape the sides and bottom of the bowl then process another 30 seconds or until well blended.
Open, drain, and rinse the chickpeas. Add half of the chickpeas to the food processor and process for 1 minute. Scrape sides and bottom of the bowl, then add remaining chickpeas and process until thick and quite smooth; 1 to 2 minutes.
Add the roasted peppers and continue to process for 1 to 2 minutes or until smooth. If the hummus is too thick or still has tiny bits of chickpea, with the food processor turned on, slowly add 1 to 3 Tbsp of water until you are happy with the consistency.
Taste for salt and adjust as needed.
DONE!
