Make the Paleo pesto: In a small food processor, combine the pepitas, garlic, and a few pinches of salt and pepper. Pulse until combined. Add lemon juice and basil and pulse again. With the blade running, drizzle in the olive oil and purée until smooth. Taste and adjust seasonings.
Heat the bottom of a large skillet with ½ to 1 tablespoon of olive oil over medium heat. Add the asparagus and let cook for 1 minute. Add ½ inch of fresh water to the pan and cook, covered, 6 to 8 minutes or until just tender. During the last 2 minutes of cooking, add the artichoke hearts, 1 tablespoon fresh lemon juice and a pinch of salt and cook until warmed through.
