Sorry, I guess it wasn't obvious that I wasn't asking but linking to somebody's answers.
According to link above (the Union of Orthodox Rabbis), you should use a glass that holds 3.3 fluid ounces of wine and drink more half for each of the four cups; eat more than a third of a matzo; and consume at least 0.7 fluid ounces of ground horseradish, 80 square inches of lettuce leaves or 15 square inches of stalks. Moreover, the drinking of each cup of wine and the eating of the matzah and maror should be completed within four minutes. L'chiam!
And according to Rabbi Shlomo Riskin, an Ashkenazi can eat kosher-for-Passover food that's been cooked with
kitniyot, as long he doesn't eat the
kitniyot itself, which is no doubt a great relief in such mixed marriages.
Of course, one should consult one's own rabbi in all such matters. I am not a halachic authority nor do I play one on TV.
