Brother, start whatever two things will make you the most happy to pick and eat. 

If you are going to have a couple containers, tomatoes, herbs, peppers, are great. If you are going to start some in-ground or raised beds, anything you want. 

Where are you located, or what is your zone and growing season like? 

 I was thinking 1 or 2 raised beds. I live in northern New England, we have a temperate climate with a growing season of late May to early October, about 50-80deg Fahrenheit. 🤙🏼
