Preheat oven to 400°
For the chickpeas, mix all ingredients EXCEPT the avocado and place them on a baking sheet. Bake for 25 minutes or until nice and crispy.
For the Lemony Potatoes, in a large baking dish, mix all the ingredients together and roast in the oven for about 40-45 minutes.
While those are both baking, make the tahini and romesco sauce.
For the tahini sauce, mix all the ingredients in a bowl and set aside on the counter.
For the romesco sauce, add all the ingredients into a food processor and mix well. It should look a little chunky.
Once the chickpeas and potatoes are almost finished cooking, heat a large skillet and add the olive oil and spinach. Cook for 2 minutes and then add the remaining ingredients and cook until slightly wilted...about another 3 minutes.
To plate, add the romesco sauce, then top with the chickpeas, potatoes, spinach, and sliced avocado. Drizzle with the lemon tahini and serve.
