DP bought me a mini greenhouse for mothers day (the little plastic yeates one) and the following seeds:

* Red Onion
* Snow Peas
* Carrot
* Cucumber

Today i bought the following herbs:
* Garlic Chives
* Mint
* Oregano
* Parsley

I am going to plant some of the herbs in a pot near the kitchen door and then put the rest in the veggie garden we are working on.

1. Will all 4 herbs be ok in 1 longish rectangular pot?

2. With the veggies can all of them be started in the greenhouse and then transplanted to the veggie patch?

3. What are some other easy fruits/veggies we can try growing?
I would really like to try lettuce, watermelon, tomato, capsicum?

Any hints on the best possible way to do this would be greatly appreciated.
