Prepare a campfire or preheat a grill to medium-high heat. If using a campfire, make sure you have a grill grate or cast iron skillet to cook the hash.
Heat a large cast iron skillet or heavy-duty aluminum foil pan over the fire or grill. Add the olive oil and let it heat up.
Add chorizo or sliced Polish sausage to the skillet and cook until browned and slightly crispy, stirring occasionally.
Add diced potatoes to the skillet and cook for about 10 minutes, or until they are slightly tender. Stir occasionally to prevent sticking.
Add the chopped onion, red bell pepper, green bell pepper, and minced garlic to the skillet. Cook for another 5 minutes, or until the vegetables are softened.
Season the hash with salt and pepper to taste. Be careful with the salt if your sausage is already salty.
Continue cooking the hash for another 10-15 minutes, or until the potatoes are fully cooked and golden brown. Stir occasionally to ensure even cooking.
Make little divots in the hash before you crack each egg into its own little well. Cover the skillet with a lid or foil and allow the eggs to cook until set.
Once the hash is cooked to your liking, remove the skillet from the fire or grill. Let it cool slightly before serving.
Serve the campfire hash hot, either directly from the skillet or transferred to a serving dish.
Optional toppings like shredded cheese, chopped green onions, or hot sauce can be added according to your preference.
