Heat 1 tbsp of olive oil or any cooking oil to a medium sauté pan. First cook plant based sausages according to package instructions. Remove from heat, chop into smaller bite sized pieces and set aside.
Add additional cooking oil to pan. Add onions, eggplants, zucchini and peppers. Let cook until soft. Feel free to add additional spices, but the marinara sauce will do just that.
In the meantime, cook pasta according to package instructions. Make sure to salt the water
While pasta is cooking, add marinara sauce and extra salt to pan with veggies. Add in the plant based sausage. Add some water in the jar (about a cup) and pour in the pan to thin out the sauce. Let simmer for a couple of minutes.
When the pasta is finished, drain and rinse. Add into pan with marinara sauce. Turn of heat and mix pasta in well. Serve while hot
