Preheat the oven to 350 degrees F. Spread the french fries on a baking sheet and bake until golden and warmed through, about 10 minutes.
Put the garlic, almonds and olive oil in a food processor and pulse until finely ground. Add the french fries, lemon juice, 1 1/4 cups water and 1/2 teaspoon salt and pulse until almost smooth. Season with salt and pepper. Transfer to a bowl and drizzle with olive oil. Serve with pita chips and/or vegetables.
