Preheat oven to 350°F. Place 24 silicone muffin liners on a rimmed baking sheet (or split up onto 2 baking sheets). If not using silicone muffins liners, grease two 12-cup muffin tins with coconut oil or olive oil.
Cook the chorizo in a skillet until completely cooked through, breaking up into small pieces with a wooden spoon. Drain out any extra grease.
Add approximately 1 tsp each of the onion and bell pepper to the bottom of the muffin cups. If you have leftovers, divide them evenly in the cups.
Divide the chorizo evenly between the 24 muffin cups.
Beat all the eggs in a large bowl and add salt and pepper. Whisk until smooth, making sure to get all the yolks incorporated.
Scoop 1/4 of the whisked egg into each muffin cup. If there are any leftover eggs, divide evenly or fill up any smaller cups.
Sprinkle the hot pepper on top of all the muffin cups evenly.
Bake in the preheated oven for 20-25 minutes, or until a knife inserted in the egg comes out clean.
