How to make paleo meatloaf
Cut the onions, peppers, and garlic.
These ingredients will all be sauteed in the olive oil together, so you'll need to first cut them into small pieces. Aim for pieces the size of your pinky fingernail.
You'll be using a sharp kitchen knife or chef's knife for this step, so be careful not to cut your fingers. If you prefer not to mince garlic, you could also use a garlic press to crush it into small pieces.
