Add chickpeas, roasted beet, tahini, lemon juice, and garlic to a food processor and pulse until roughly combined.

With the processor running, drizzle in the olive oil and blend until smooth.

Add cumin and salt, then blend again while gradually adding cold water until you reach your desired creamy consistency.

Taste and adjust seasoning as needed, then transfer to a serving bowl and drizzle with additional olive oil before serving.
