Preheat oven to 425 degrees F (218 C).
Place garlic cloves with skin still on and whole jalapeños on a baking sheet. Drizzle garlic cloves with a small amount of oil of choice (avocado or olive are best) and roast for 15-18 minutes, flipping jalapeños once to ensure even roasting. If the garlic cloves get too roasty-looking, take them out.
Once done, remove from oven and set garlic aside.
Wrap jalapeños in foil to steam for a few minutes. Then carefully peel away skin and remove seeds. Be sure to wash your hands afterwards!
To a blender or food processor, add slightly drained chickpeas, oil, cilantro, avocado, salt, cumin, lime, lemon, roasted jalapeños (start with one and work your way up to desired spice level), tahini and peeled garlic cloves (you should be able to peel away the skin or just squeeze the garlic out).
Blend until creamy and smooth, scraping down sides as needed. Taste and adjust seasonings as desired. (I used two medium jalapeños and it was plenty spicy // amount as original recipe is written // adjust if altering batch size).
To prepare toasted pumpkin seeds, preheat oven to 350 degrees F (176 C) and toss pumpkin seeds in 1 Tbsp oil + a pinch each salt, pepper and cumin (amounts as original recipe is written // adjust if altering batch size).
Spread on a baking sheet and roast for 8-12 minutes. Add to top of hummus, along with another drizzle of olive oil (optional) and fresh cilantro.
Serve hummus with veggies, tortilla chips or pita. Leftovers keep well in the fridge, covered for up to 1 week, though best when fresh.
