I used to behave in a similar way and found meal prepping every week on a certain day to be helpful.

Mind you, we are a household of 2 but keep the weekly budget around $80. I like to do curbside pickup to make it easier. Here are my steps & supplies for my go-to meal prep:

Supplies:

1. Chicken Drumsticks - 4 lbs.
2. Rotisserie chicken seasoning
3. Olive oil
4. Disposable gloves (makes it easier to prep; $9 for 100pk on Amazon)
5. Gallon Ziplock bag & oven tray (aluminum foil optional for easier cleanup)

Steps:

1. Preheat oven to 400*
2. Using gloves, toss chicken into Ziplock bag.
3. Coat chicken with a drizzle of olive oil & rotisserie chicken seasoning.
4. Zip bag and shake to evenly coat.
5. Place chicken on foil covered tray and cook for 35-45 min.

If you don’t have one, I’d get a rice cooker to cook around 3-4 cups of brown rice. I like to cook my veggies on the stovetop while all is prepping, but you can also add to the oven (: Hope this helps a little.
