Chicken Spaghetti--No Velveeta Or Cream Soups - cooking recipe

Ingredients

1 (13 ounce) can chicken breasts, chopped (or 1-2 diced chicken breasts)
1 medium onion, chopped
3 garlic cloves, minced
1/2 red bell pepper, chopped
1/2 teaspoon salt
1/4 teaspoon pepper
1/2 teaspoon thyme
1/2 teaspoon oregano
1 tablespoon olive oil
1 (28 ounce) can diced tomatoes
1 (4 ounce) canned diced green chiles (mild)
1 (13 1/4 ounce) package whole wheat spaghetti
1 (12 ounce) can evaporated milk
3/4 cup milk, divided
1/4 teaspoon ground mustard
1/8 teaspoon garlic powder
1/2 teaspoon salt
2 teaspoons cornstarch
8 ounces cheddar cheese, grated

Preparation

Preheat oven to 350 degrees.
Heat oil in a skillet. Add chicken, onion, garlic, and bell pepper. Sautee for about 5 minutes or until veggies are tender.
Add tomatoes, chiles, salt, pepper, thyme, and oregano. Let simmer while you do other steps.
Boil spaghetti until al dente (about 6 minutes).
While spaghetti is cooking, in a medium saucepan cook evaporated milk, 1/2 c of the milk, ground mustard, garlic powder and 1/2 teaspoon salt. Bring to a boil and reduce to a simmer. Stir regularly as it will stick to bottom of pan.
Whisk the cornstarch and the remaining 1/4 c of milk together. Then, whisk it into the simmering mixture. Continue to simmer, whisking constantly, until the sauce has thickened and is smooth, about 2 minutes.
Off the heat, gradually whisk in the grated cheese until melted and smooth.
Spray a 9x13 casserole dish with nonstick spray. Mix the drained spaghetti, chicken/tomato mixture, and cheese sauce. You could probably eat it at this point, but I chose to cook mine in the oven for 20 minutes.
