I'm so excited for spring/summer and all the locally grown fresh veggies that will be available for topping homemade pizzas. Tomatoes and basil are always a staple in our mom's garden and they make great pizza toppings. unfortunately, Not everyone has the room to make a big back yard garden but you can get great big pots and put them on your porch or even the roof for more urban gardening. I found a video online with a a great idea for planting a Pizza Pot- planting pizzalicous herbs and veggies in pots.
Plant the tomato in the center of a large pot and plant herbs like basil and oregano around it. I'd pick a small tomato good for topping a pizza like Roma or cherry tomatoes. If you really want to get crazy you can even make sauce with them, though I'm not sure which tomatoes are best for that. If you have room for more than one pot, try planting things like onions, garlic, green and red peppers or chilies. If you grow enough basil you could even make pesto for the pizza.
Spinach, eggplant, squash and squash blossoms are also really great on pizza, though they may require more room. If you had the room (and proper conditions) you could even gets spores and plant mushrooms. Fresh vegetables always make a difference on a good pizza.
