Ingredients

  • 1-16 oz. pkg. large rigatoni
  • 4 cups broccoli flowerets
  • 2 Tbsp. butter
  • 2 Tbsp. flour
  • Salt and pepper
  • 4 cups 2% milk
  • 1 cup 4 oz. Swiss cheese, shredded
  • 4 oz. Cheddar cheese shredded
  • 3 - 4 oz. cans chunk tuna in water drained and flaked (12 oz. of tuna)
  • 2-3 medium tomatoes sliced in 1/4" slices

Instructions

  • In a large pot, cook pasta in boiling salted water for 5-6 min. or about 5 min. away from al dente according to the package. Add the broccoli and cook for the last 5 min. Drain well and return to saucepan.
