Beef and Noodle Stir Fry

Ingredients:
8 oz lasagna noodles - broken in half and cooked (I also sort of ripped them into smaller pieces once they were cooked)
12 oz sirloin - cut into bite sized pieces
3 TBSP flour
2 TBSP butter
2 TBSP olive oil
2 cups grape or cherry tomatoes - cut in half
1/2 onion - chopped
1 1/2 - 2 cups sliced mushrooms
*1/2 red bell pepper - sliced (optional)
salt, pepper & red pepper flakes to taste

Heat olive oil in a large pan over medium heat. Saute onions, bell pepper, onion and tomatoes until the onion is barely tender. Add butter to the pan and sprinkle veggies with flour; stir until well combined and slowly add broth. Simmer 1 minute and add meat. Stir and simmer until sauce has thickened and meat is cooked through. Add cooked noodles and season to taste.
