It’s sometimes recommended that you don’t try to grow vegetables that are readily available at your local supermarket.  If a particular vegetable is inexpensive, you might want to skip growing it and just purchase it.   Of course, it can be difficult to find good quality in some types of vegetables, so if there is a big difference in quality, that could be a great reason for growing that type.   Tomatoes – Although technically a fruit, its savory nature leads to this little beauty being considered a vegetable by most people.  Tomatoes found in stores are usually picked nearly green and then ripened artificially.   This is done to ensure they are tough enough to survive shipping without being smashed, and so they last longer on the shelves.  Since tomato quality can be really poor in stores, this is a very good choice.  Tomatoes are the most popular choice for vegetable gardeners, because they probably have the most noticeable difference over store bought.   Lettuce – Although iceberg lettuce doesn’t very that much from store to home, leaf lettuces and other fancy lettuces can taste much sweeter and crisper if grown at home.  Plus, exotic lettuces can often be very expensive.   Peas – Peas can be very hard to find fresh.  Canned peas are often mushy, and although frozen peas are certainly better than canned, they still pale in comparison to fresh peas.  Tiny baby peas are sweet, delicate, and delicious, making them well worth the effort.   Carrots – Store bought carrots are often woody, tough, and bitter.  Even organic carrots often carry a strong bitterness caused by being kept at temperatures that are too cool for too long.  Fresh carrots are generally very sweet and delicious.   Radishes – Radishes are cheap and easy to find in stores, but most store bought radishes are already turning pithy.  If you’ve ever bitten into a radish that was dry and spongy inside, you’ll understand how bad pithy radishes are.  Fresh radishes are delightful!   Greens – Although most greens are readily available in stores, they’re often yellowing and wilted by the time you buy them.  By growing them yourself, you can be sure you have fresh greens when you want them.   Asparagus – Fresh asparagus is often ridiculously expensive, and canned asparagus is mushy and horrible!  The only way to get affordable asparagus that isn’t mushy and bland is to grow it yourself.   Peppers – Peppers in stores are often shriveled and pathetic.  Plus, peppers that aren’t standard green peppers can often be very expensive.  My local store has sold red peppers for as much as $2.99 each, which is crazy!  Grow your own and save money.   Cucumbers – Store bought cucumbers are often bitter and dry.  If you’ve ever had a dried out, semi-hollow cucumber, you’ll understand the importance of growing your own!   Corn – Sweet corn is a delight to eat when it’s freshly picked.  Corn is extremely sensitive to being off the stalk.  Once it’s been off the stalk for 6 hours, it starts to deteriorate rapidly.  You’ve never had corn until you’ve eaten it cooked fresh.
