A remix of Judith Barrett's version - Fagioli, page 36. hs note:I like the taste and texture of beans cooked from scratch, but I don't see why you couldn't make this using canned chickpeas. Start with two 14-ounce cans, drained and rinsed. Cook the potato on its own. This should get you in the ballpark.
1 sweet baguette, cut into 1/4-inch thick slices
3 tablespoons olive oil
a couple pinches of salt
1 large garlic clove, peeled.
1 cup dried chickpeas, rinsed and picked over
1 small new potato (Yukon Gold, Yellow Fin, etc), peeled and quartered
5-6 handfuls of spinach, washed well
1 small red onion, chopped
zest of one lemon
juice of 1/2 lemon, approx.
salt and pepper
1/4 cup extra virgin olive oil
chives for garnish (opt)
Prepare beans and potato:
Soak the garbanzos overnight. Drain soaking liquid, and refill with enough water to cover the beans by about an inch. Bring water to a boil, reduce heat, and allow to simmer until beans are tender. Add the potato to the pot (or cook it in another water-filled) until tender, another 10 minutes or so. Drain any extra water at this point and set beans/potato aside.
Preheat oven to 350. In a large bowl toss the baguette slices with the olive oil and salt. Arrange in a single layer on a baking sheet and place in the oven until golden, about 10 minutes. Remove from oven, let cool for a couple minutes and rub each crostini with the clove of garlic - don't go overbboard, raw garlic is strong!
Add a splash of olive oil to a hot skillet, and throw in the spinach. It should collapse within 10 or 20 seconds. Immediately remove from heat and salt to taste.
Combine the chickpeas, potato, spinach, 1/4 cup red onions, lemon zest and juice, and a few big pinches of salt in a food processor. With the machine running drizzle in the olive oil. Chances are your mixture is on the dry side at this point and you may need to add warm water a few tablespoons at a time until the spread is a rich, creamy consistency. Season carefully, if you under salt the flavor will be flat. If you need more acidity, and a bit more lemon juice.
Put a spoonful of the spread on each crostini. Finish with a drizzle of good-quality extra-virgin olive oil, and a sprinkling of the red onions.
