Preheat the oil in a frypan over a medium heat and sauté the onion, garlic and mince until browned and crumbly.
Add the taco seasoning, red kidney beans and tomato paste and stir over the heat for 5 minutes.
Preheat the 4 Slice Sandwich Press until the heating light turns off.
Place a tortilla onto the sandwich press plate and fill with half of the avocado, sour cream, cherry tomatoes, cheese and bean mixture. Place a second tortilla on top and close the lid for 3 minutes or until golden brown.
Repeat once more and slice each quesadilla into 4 pieces.
