Fry the peppers, tomatoes and jalapeño slices in 2 tablespoons of oil and add the taco sauce. Season with salt and pepper if necessary. Let everything still simmer for a while. Season the minced meat with Fajita Seasoning Mix and mix it with the onions. Fry for 3-4 minutes at medium heat.
Place two tortillas on a baking plate with baking paper, add the minced meat and vegetable-taco-mixture and put the chips in it.
Let everything bake in the oven at 180°C (circulating air) for around 10-15 minutes.
