I agree that you could start offering him whatever you're having, if he's keen (so long as it's safe, of course!). Have you considered taking a baby-led weaning approach? My LO's menu today consisted of:
Breakfast: porridge (lumped on tray for her to eat on her own), a whole finger banana and cubes of papaya
Lunch: brown rice with prawns and mixed veges in garlic pepper sauce (she grabs the prawns by the tail and gums/sucks away at them), followed by cubes of watermelon
Dinner: cottage pie (messy but delicious)
Lots of fun!
