Penne rigate in a spicy sauce

Penne rigate pasta with a spicy vegetarian sauce is just a complete meal. I just binge on such recipes. Here it goes...

Ingredients:
Penne pasta - 1 cup
Carrot - 1 nos
Capsicum - 1 nos
Green peas - 1 small tin
Tomato puree - 2 tbsp
Tomato paste - 1 tbsp
Veg stock cube - 1 nos
Chilly powder - 1 tsp
Pepper powder - 1 tsp
Onion paste - 1 tsp
Garlic paste - 1 tsp
Salt for taste
Oil - 2 tbsp

Method:
Cook pasta in hot boiling water for 10 min or till its done. Strain water using a colander and keep the pasta aside. Cut carrots into thin strips, dice capsicum and keep aside. In a wok, heat oil, saute onion and garlic paste. Add chilly powder and give it a stir. Add all the remaining ingredients except pasta and saute for 2 min. Add some water if required and continue to cook for another 2 min. Add the pasta and salt if required. Toss well until its well coated with the spicy sauce. Serve hot.

Note:
Can top it with cheese. I have excluded it, just to keep the pasta healthy. If you don't prefer the veg stock cube, then can add dried herbs of your choice like oregano, thyme, sage, etc. for flavour.
