# Expert Advice:

01 -
  • You can eat breakfast in bed, in the car, or straight from the jar without a single dirty dish.
  • The oats soak up all the peanut butter richness overnight, so every spoonful tastes indulgent but fuels you for hours.
  • It's wildly adaptable, you can make it sweeter, thicker, fruitier, or more dessert-like depending on your mood.
  • With nearly 40 grams of protein, it keeps you full and steady all morning long.
02 -
  • If you skip the Greek yogurt, the oats will be thinner and less tangy, so add an extra tablespoon of chia seeds to thicken them back up.
  • Protein powder can make the oats weirdly thick and chalky if you don't add enough liquid, so whisk it into the wet ingredients first and loosen with water if needed.
  • Don't add fresh berries the night before unless you want pink, soggy oats, stir them in just before you eat.
03 -
  • Make three or four jars at once on Sunday night so you have breakfast ready all week, just add fresh fruit each morning.
  • If the oats taste bland, you didn't add enough salt or vanilla, a pinch of each makes a huge difference.
  • Let the jar sit on the counter for 10 minutes before eating if you don't like cold oats, they'll soften and warm up just enough.
