new fruits and vegetables

we have had the same plants for a long long time. and some of them are edible, which is my topic. for as long as i remember, there isn't anything new added to plants that you can eat, there are carrots, potatoes, beetroot, wheat (well, bread) and you can technically include melon. my idea is to add lettuce/cabbage (or both if youre generous to me) which you can eat straight up for example like beetroot, and you could make a new food with them, like a salad. tomatoes and bell peppers would be good too but im not gonna include an essay about those.
