Tomatoes are an excellent option for people who want to grow something that they can eat on its own. Fresh Tomatoes make a world of differences in a variety of sauces, etc., but takes slightly longer to grow and more maintenance. 

Lettuce is an essential ingredient in every salad. Lettuce is sprouted within two weeks and is fully grown and ready to eat by 3 to 5 weeks. 

Basil is the best for people who want a low maintenance plant that can be used in a variety of dishes. Its pleasant aroma compliments a variety of other flavors and is produced in relative abundance. 

Thyme is another very popular spice. Like basil, it is easy to grow and has a diverse range of dishes to be put in. Its aroma tends to lean warmer.
