We're not suggesting you start your own farm or even that you plant an entire vegetable garden. However, there are some vegetables that are easier to grow than you might think, and you don't even need a yard to do so. These include peppers, tomatoes, lettuce, cabbage, and plenty of others. You can grow all of these in your home if you have access to enough sunlight, and they don't even take that much care.
Growing your own vegetables will also help cut down on random trips to the grocery store as you're less likely to run out of perishable foods as often if you have some growing in your home.
