First brown your meat. I like to use ground turkey or turkey Italian sausage. But ground beef or pork works well too. If you are not using sausage, add some seasoning for flavor-I used and Italian seasoning with basil, rosemary, garlic and thyme.
Next boil the pasta shells till they are "al dente", usually 8 min or so. Once they are cooked, transfer them to a bowl of ice cold water. It will keep them firm and make them easier to fill. Put them in the fridge while you do the next step.
With the pasta shells cooling in the fridge, finish preparing the filling. Combine the meat, veggies, ricotta, and pasta sauce in a large skillet and mix it while it is simmering. Preheat oven to 375 degrees.
You will need:
1 box (12ozs) Jumbo Shells
1lb Italian sausage (casings removed) or ground meat of choice
1tbsp minced garlic
16oz Ricotta cheese (I like to use the reduced fat kind)
10oz package frozen spinach-thawed and squeezed dry
1c grated cheese (I used a 50/50 split of mozz and parm)
1 jar of pasta or marinara sauce-use half for the filling and half to pour over them to bake
Seasonings-either use a pre-made Italian seasoning, or use fresh chopped basil, rosemary and thyme
