Cook vegetables by boiling or steaming until tender.
Meanwhile, fry onion and garlic in a little olive oil or butter for a few minutes, until tender and starting to brown. Remove from heat and set aside.
Once vegetables are cooked, strain if necessary and put into a blender. Add onion, garlic, cheese, basil and pepper.
Blend to make a sauce. If the mixture seems too thick and dry, start adding in some water and blending until it turns into a thick sauce.
Cook pasta according to packet directions.
Drain pasta, return to pot, and immediately add the sauce. Mix to combine.
Serve with a sprinkle of grated cheese.
Makes 2-3 toddler sized servings.
