"I made several changes to this recipe. Meat & Potatoes the same; used 1 medium onion, diced;1 green pepper, diced; garlic, fresh mushrooms,sliced ripe olives & fresh tomatoes, the same. Only next time, I will place each fresh tomato in boiling water for a short time & peel the skin off & dice the tomato, so the skin will not come off the tomato & float in the sauce, as mine did. For the seasoning, I used 1 tsp. Italian seasoning, 1 tsp. dried basil, 1/2 tsp. seasoned salt & 1/4 tsp. pepper. Those were the only other changes that I made. This did not make a lot & I may double the recipe next time, but it was delicious & very Italian tasting & a nice presentation. Thanks for the recipe!"
