Remove stems from spinach (If they bother you - they bother me, so I generally always remove them. If you're ok with them, you can skip this step.) Set aside.
Cut cherry tomatoes in half and set aside.
Cut sausages into 1/4" pieces.
Heat large frying pan over medium-high heat.
Add olive oil and swirl to cover bottom of pan.
Add sausage pieces to pan and cook for 15 minutes or until browned and cooked through.
Add spinach, garlic powder, onion powder, salt and pepper.
Toss sausages and spinach together in frying pan.
Cook for 5 minutes, stirring often, until spinach is wilted.
Add cherry tomatoes and cook for 5 minutes - tomatoes should start to pop and release juice.
Remove to serving bowl and sprinkle with Parmesan cheese.
