A comforting, creamy mac and cheese with hidden steamed cauliflower and carrots blended into the cheese sauce, designed to stay warm and creamy in a thermos for lunches.
Preheat the thermos with boiling water before filling to maximize heat retention. Stir the cheese sauce frequently while cooking to avoid burning and keep it silky. If the sauce is too thick after adding pasta, stir in a splash of milk to loosen. Use a mix of sharp and mild cheddar for balanced flavor and smooth melt. Puree veggies finely to avoid texture changes. Avoid boiling the sauce after adding cheese to prevent graininess.
