  • 2 cups | 290 gr gluten-free egg noodles
  • 5.3 oz | 150 gr frozen green beans
  • 1 tbsp garlic infused oil
  • 7 oz | 200 gr. canned tomatoes diced
  • 2,6 oz | 75 gr | 1 medium carrot cut into small dices
  • 5 oz | 142 gr can of tuna
  • ½ cup | 40 gr. shredded cheddar cheese
  • 2 tbsp chives


  • Preheat oven to 375ºF /190ºC on grill.
