Ingredients

1 piece yellow bell pepper
1 piece red bell pepper
1 piece green bell pepper
1 piece yellow onion
1 piece green onion
2 large zucchinis
2 tbsp olive oil divided
2 lb ground beef
1 can tomato sauce
2 cups cheddar cheese
1 piece avocado

Fajita Seasoning

1/2 tsp chili flakes
1 tsp cayenne pepper
1 tsp garlic powder
1 tsp ground cumin
1 tsp paprika
1/2 tsp black pepper ground
1 tsp salt

Instructions

Chop all bell peppers and onions into slices and the zucchini in half slices. Set aside.
Add one tbsp of olive oil into a large skillet and heat it over medium heat. Then, add chopped bell peppers and yellow onion. Sauté until they begin to soften. Then, add zucchini. Stir over the stove until the zucchini is fork-tender. Add fajita seasoning and combine. Set aside.
Add one tbsp of oil into a large skillet or pan over medium heat, then add green onion and stir for two minutes to soften. Brown the ground beef and then drain off excess oil.
Next, add canned tomato and stir until the liquid has evaporated. Season with salt and pepper to taste.
Transfer ½ of the cooked veggies to a baking dish and arrange them at the bottom. I’ve used a 10’’ round baking dish. Then, create a ground beef layer, followed by 1 cup of cheddar cheese. Next, finish with the remaining veggies and ground beef. Top with the extra cup of cheese.
Bring it to a preheated oven at 375F until the cheese has fully melted.
Serve warm with chopped avocado, garnished with fresh parsley or cilantro

Notes

Tips

Replace ground beef with texturized soy to have a vegetarian meal.
This casserole could feed a crowd if served with tortillas as a traditional Mexican meal.
Replace ground beef with ground pork if you desire.
Store leftovers, covered, in the fridge for up to five days. Reheat them for 8-10 minutes in the oven at 350F.
