My husband is from Uruguay. We actually grow "Zapallitos" from Uruguay every summer using seeds from there. These Original Squash look similar to a winter butternut, but are a summer variety, similar in taste to our Zucchini's. <br/>The recipe is great as it is, although any stuffing recipe works well with squash and I often joke, I never make the same recipe twice, alway's adding or subtracting ingredients depending on what I have on hand at any given time.<br/>I usually, sauté onions, peppers and garlic, then add it to the browned beef and breadcrumb mixture. <br/>In Uruguay, we usually cut the squash in half, then blanch in boiling water for 3-5 minutes then in cold water, to scoop out the seeds easier. We then drain them a bit, and also add some of the small seeds and pulp in with the stuffing mixture.<br/> My husbands personal topping is a white sauce, that has been flavored with grated parmesan cheese and nutmeg. Then baked in the oven for about 30 minutes. I have posted a foto of my recipe using Uruguayan Zappallitos.
