Place the squash on a rimmed baking sheet. Toss with the olive oil, season with salt and pepper and spread out in a single layer. Roast for 30-35 minutes, until the edges are brown and it is tender when pierced with a fork.
Place the black-eyes peas in a pan and cover with water by 3 inches. Salt and bring to a boil over high heat. Reduce the heat to simmer and cook for 20 more minutes, stirring occasionally. The peas should be tender, but still firm. Drain and rinse under cold water.
Place the ingredients for the sweet and spicy vinaigrette in a mason jar and cover with a lid. Shake to emulsify.
Place the squash, peas, bell pepper, jalapeno pepper, marjoram, parsley, salt and pepper, and ½ cup of the vinaigrette and toss gently. Transfer to a serving platter and top with the crumbled goat cheese.
Notes
Can use any winter squash - acorn squash or delicata or other edible pumpkin. In place of marjoram - can substitute oregano or thyme.
