What’s the best way to prepare the dish I see in my head?

So I’m trying to slim down and I’m looking to meal prep my lunches. I’m a creature of habit so I’m only going to make the same meal for each day of the week. I’m trying to go for a sort of southwestern chicken bowl but I’m a total beginner at cooking. Here are my ingredients:

• Raw chicken tenderloin

• Black beans (canned and dry)

• Brown rice (big bag)

• Corn (Canned)

Do I just dump it all in the crock pot? Do I need to cook anything separately? What seasonings should I use?
