Slice the cherry tomatoes in half and add them to a baking dish. Cut the peppers into slices and add them too along side the balsamic onions, garlic cloves (skins on and crushed with the back of a knife), red pepper flakes, herbs and fennel seeds.
Add 2 tbsp of olive oil, 1 tsp balsamic vinegar and a good pinch of salt and pepper, bake in the over for 10 minutes to soften.
Removed the softened veg and place the sausages on top. Bake for another 15 minutes, turn the sausage and bake for a further 10-15 minutes. The sausages should be browned, cooked through and the veg soft and stew like.
Serve with crusty bread, salad or creamy mashed potatoes.
Notes
Top Tips For Making This Italian Sausage Bake;
To make the stewed veg a little saucer add 2-4 tbsp of white wine
Add sliced fresh chilli for an extra kick
You could sub the sausages for salmon fillets or chicken
Bake the veggies first for 10 minutes before adding the sausages or the veg won't be soft and saucy enough
If the sausages aren't browned enough place them under a broiler/grill for a couple of minutes
