In a high-speed blender, or food processor, add the pepitas, jalapeño, green onions, and garlic. Pulse for about 30 seconds until you have a fine crumb. Add in the cilantro, red wine vinegar, lime juice, orange juice, and salt. Pulse until the mixture is mostly smooth. With the motor running on low-medium, stream in the olive oil. Blend until completely smooth. If the blender needs a bit of help, slowly stream in warm water in tablespoon increments until the desired texture is reached. It will be a bit thinner than a pesto, but still textured. Refrigerate until ready to serve.
