Vegetables
In this video you learn language signs for foods like mushrooms, tomatoes, broccoli or peas; Now I'll teach you signs for vegetables. We're going to be healthy here. Carrots, carrot; avocado, there's no sign for avocado. I usually see people finger spell that one. Mushrooms, mushroom; salad, salad; lettuce, lettuce; tomato, tomato. That's a hard one; I'll show you that one again, tomato. Beans or peas, they both use the same sign; peas, beans. Broccoli is another one that doesn't have a sign; you might describe what it looks like. You might say that it's green and that it's shaped a certain way, and you might say that it's healthy or you don't like the taste of it. Anything that'll help you describe a particular vegetable. Practice those vegetable signs
