Grow what you are interested in eating. Always a disappointment growing something only to find you don’t like it. I did that with artichokes last year. I always try one thing new and different so didn’t devote much space to them, but was still a waste.
For peas either start them in module pots or plant direct, just in a shallow drill. Rather than netting, I usually support them by putting in a line of canes and horizontal string, about 20cm apart.
Look at companion planting too, for things that will work together. In a border you could do a row of onions or leeks at the back, as these are slow growing, then your peas and look at lettuces or swiss chard at the front. Chard is great, easy to grow, tends not to bolt and you can use it in cooking like spinach or the smaller leaves as salad leaves. It lasts well to. Even after being burried in snow, I still have some of last years out there.
